-/**
- * @mainpage Welcome to PJLIB!
- *
- * @section intro_sec What is PJLIB
- *
- * PJLIB is a small foundation library written in C for making scalable
- * applications. Because of its small footprint, it can be used in embedded
- * applications (we hope so!), but yet the library is also aimed for
- * facilitating high performance protocol stacks.
- *
- * PJLIB is released under LGPL terms.
- *
- * @section download_sec Download
- *
- * PJLIB and all documentation can be downloaded from
- * http://www.pjproject.net.
- *
- *
- * @section how_to_use_sec About This Documentation
- *
- * This document is generated directly from PJLIB source file using
- * \a doxygen (http://www.doxygen.org). Doxygen is a great (and free!)
- * tools for generating such documentation.
- *
- * @subsection doc_ver_subsec Version
- *
- * This document corresponds to PJLIB version 0.3-pre2.
- *
- *
- * @subsection find_samples_subsec How to Read This Document
- *
- * This documentation is laid out more to be a reference guide instead
- * of tutorial, therefore first time users may find it difficult to
- * grasp PJLIB by reading this document alone.
- *
- * However, we've tried our best to make this document easy to follow.
- * For first time users, we would suggest that you follow these steps
- * when reading this documentation:
- *
- * - continue reading this introduction chapter. At the end of this
- * chapter, you'll find section called \ref pjlib_fundamentals_sec
- * which should guide you to understand basic things about PJLIB.
- *
- * - find information about specific features that you want to use
- * in PJLIB. Use the <b>Module Index</b> to find out about all
- * features in PJLIB (if you're browsing the HTML documentation,
- * click on the \a Module link on top of the page, or if you're
- * reading the PDF documentation, click on \a Module \a Documentation
- * on the navigation pane on the left).
- *
- * @subsection doc_organize_sec How To's
- *
- * Please find below links to specific tasks that you probably
- * want to do:
- *
- * - <b>How to Build PJLIB</b>
- *\n
- * Please refer to \ref pjlib_build_sys_pg page for more information.
- *
- * - <b>How to Use PJLIB in My Application</b>
- *\n
- * Please refer to \ref configure_app_sec for more information.
- *
- * - <b>How to Port PJLIB</b>
- *\n
- * Please refer to \ref porting_pjlib_pg page.
- *
- * - <b>Where to Read Samples Documentation</b>
- *\n
- * Most of the modules provide link to the corresponding sample file.
- * Alternatively, to get the list of all examples, you can click on
- * <b>Related Pages</b> on the top of HTML document or on
- * <b>PJLIB Page Documentation</b> on navigation pane of your PDF reader.

+
+/**
+ * @mainpage Welcome to PJLIB!
+ *
+ * @section intro_sec What is PJLIB
+ *
+ * PJLIB is a small foundation library written in C for making scalable
+ * applications. Because of its small footprint, it can be used in embedded
+ * applications (we hope so!), but yet the library is also aimed for
+ * facilitating high performance protocol stacks.
+ *
+ * PJLIB is released under LGPL terms.
+ *
+ * @section download_sec Download
+ *
+ * PJLIB and all documentation can be downloaded from
+ * http://www.pjproject.net.
+ *
+ *
+ * @section how_to_use_sec About This Documentation
+ *
+ * This document is generated directly from PJLIB source file using
+ * \a doxygen (http://www.doxygen.org). Doxygen is a great (and free!)
+ * tools for generating such documentation.
+ *
+ * @subsection doc_ver_subsec Version
+ *
+ * This document corresponds to PJLIB version 0.3-pre2.
+ *
+ *
+ * @subsection find_samples_subsec How to Read This Document
+ *
+ * This documentation is laid out more to be a reference guide instead
+ * of tutorial, therefore first time users may find it difficult to
+ * grasp PJLIB by reading this document alone.
+ *
+ * However, we've tried our best to make this document easy to follow.
+ * For first time users, we would suggest that you follow these steps
+ * when reading this documentation:
+ *
+ * - continue reading this introduction chapter. At the end of this
+ * chapter, you'll find section called \ref pjlib_fundamentals_sec
+ * which should guide you to understand basic things about PJLIB.
+ *
+ * - find information about specific features that you want to use
+ * in PJLIB. Use the <b>Module Index</b> to find out about all
+ * features in PJLIB (if you're browsing the HTML documentation,
+ * click on the \a Module link on top of the page, or if you're
+ * reading the PDF documentation, click on \a Module \a Documentation
+ * on the navigation pane on the left).
+ *

- * @section features_sec Features
- *
- * @subsection open_source_feat It's Open Source!
- *
- * PJLIB is currently released on LGPL license. We may release PJLIB under
- * additional schemes in the future (such as GPL or MPL) to incorporate
- * linking with specific application, however, one thing for sure is
- * we will NEVER be able to make PJLIB a proprietary software.
- *
- * @subsection extreme_portable_feat Extreme Portability
- *
- * PJLIB is designed to be extremely portable. It can run on any kind
- * of processors (16-bit, 32-bit, or 64-bit, big or little endian, single
- * or multi-processors) and operating systems. Floating point or no
- * floating point. Multi-threading or not.
- * It can even run in environment where no ANSI LIBC is available.
- *
- * Currently PJLIB is being ported to:
- * - x86, Win32 (Win95/98/ME, NT/2000/XP/2003, mingw).
- * - x86, Linux (user mode and as <b>kernel module</b>(!)).
- * - alpha, Linux
- * And coming up:
- * - x86, eCos
- * - ultra-II, Solaris.
- * - powerpc, MacOS
- * - m68k, PalmOS.
- * - arm, PocketPC
- *
- * No other library is known to have this extreme portability!
- *
- * @subsection small_size_feat Small in Size
- *
- * One of the primary objectives is to have library that is small in size for
- * typical embedded applications. As a rough guidance, we aim to keep the
- * library size below 100KB for it to be considered as small.
- * As the result, most of the functionalities in the library can be tailored
- * to meet the requirements; user can enable/disable specific functionalities
- * to get the desired size/performance/functionality balance.
- *
- * For more info, please see @ref pj_config.
- *
- * @subsection no_dyn_mem No Dynamic Memory Allocations
- *
- * The central idea of PJLIB is that for applications to run as fast as it can,
- * it should not use \a malloc() at all, but instead should get the memory
- * from a preallocated storage pool. There are few things that can be
- * optimized with this approach:
- *
- * - \a alloc() is a O(1) operation.
- * - no mutex is used inside alloc(). It is assumed that synchronization
- * will be used in higher abstraction by application anyway.
- * - no \a free() is required. All chunks will be deleted when the pool is
- * destroyed.
- *
- * The performance gained on some systems can be as high as 10x speed up
- * against \a malloc() and \a free().
- *
- * For more information, see \ref PJ_POOL_GROUP
- *
- *
- * @subsection os_abstract_feat Operating System Abstraction
- *
- * PJLIB has abstractions for features that are normally not portable
- * across operating systems:
- * - @ref PJ_THREAD
- *\n
- * Portable thread manipulation.
- * - @ref PJ_TLS
- *\n
- * Storing data in thread's private data.
- * - @ref PJ_MUTEX
- *\n
- * Mutual exclusion protection.
- * - @ref PJ_SEM
- *\n
- * Semaphores.
- * - @ref PJ_ATOMIC
- *\n
- * Atomic variables and their operations.
- * - @ref PJ_CRIT_SEC
- *\n
- * Fast locking of critical sections.
- * - @ref PJ_LOCK
- *\n
- * High level abstraction for lock objects.
- * - @ref PJ_EVENT
- *\n
- * Event object.
- * - @ref PJ_TIME
- *\n
- * Portable time manipulation.
- * - @ref PJ_TIMESTAMP
- *\n
- * High resolution time value.
- * - etc.
- *
- *
- * @subsection ll_network_io_sec Low-Level Network I/O
- *
- * PJLIB has very portable abstraction and fairly complete set of API for
- * doing network I/O communications. At the lowest level, PJLIB provides:
- *
- * - @ref PJ_SOCK
- *\n
- * A highly portable socket abstraction, runs on all kind of
- * network APIs such as standard BSD socket, Windows socket, Linux
- * \b kernel socket, PalmOS networking API, etc.
- *
- * - @ref pj_addr_resolve
- *\n
- * Portable address resolution, which implements #pj_gethostbyname().
- *
- * - @ref PJ_SOCK_SELECT
- *\n
- * A portable \a select() like API (#pj_sock_select()) which can be
- * implemented with various back-end.
- *
- *
- * @subsection hl_network_io_sec High-Level Network I/O
- *
- * At higher abstraction, PJLIB provides @ref PJ_IOQUEUE,
- * which promotes creating high performance network
- * applications by managing asynchronous I/O. This is a passive framework
- * that utilizes the most effective way to manage asynchronous I/O
- * on a given platform, such as:
- * - IoCompletionPort on WinNT,
- * - on Linux it can use either /dev/epoll or aio.
- * - or to fall back to use @a select()
- *
- * At even a higher abstraction, PJLIB provides @ref PJ_EQUEUE, which
- * combines asynchronous I/O with timer management and thread management
- * to fasilitate creating trully high performance, event driven
- * application.
- *
- *
- * @subsection timer_mgmt_sec Timer Management
- *
- * A passive framework for managing timer, see @ref PJ_TIMER for more info.
- * There is also function to retrieve high resolution timestamp
- * from the system (see @ref PJ_TIMESTAMP).
- *
- *
- * @subsection data_struct_sec Various Data Structures
- *
- * Various data structures are provided in the library:
- *
- * - @ref PJ_PSTR
- * - @ref PJ_ARRAY
- * - @ref PJ_HASH
- * - @ref PJ_LIST
- * - @ref PJ_RBTREE
- *
- *
- * @subsection exception_sec Exception Construct
- *
- * A convenient TRY/CATCH like construct to propagate errors, which by
- * default are used by the @ref PJ_POOL_GROUP "memory pool" and
- * the lexical scanner in pjlib-util. The exception
- * construct can be used to write programs like below:
- *
- * <pre>
- * #define SYNTAX_ERROR 1
- *
- * PJ_TRY {
- * msg = NULL;
- * msg = parse_msg(buf, len);
- * }
- * PJ_CATCH ( SYNTAX_ERROR ) {
- * .. handle error ..
- * }
- * PJ_END;
- * </pre>
- *
- * Please see @ref PJ_EXCEPT for more information.
- *
- *
- * @subsection logging_sec Logging Facility
- *
- * PJLIB @ref PJ_LOG consists of macros to write logging information to
- * some output device. Some of the features of the logging facility:
- *
- * - the verbosity can be fine-tuned both at compile time (to control
- * the library size) or run-time (to control the verbosity of the
- * information).
- * - output device is configurable (e.g. stdout, printk, file, etc.)
- * - log decoration is configurable.
- *
- * See @ref PJ_LOG for more information.
- *
- *
- * @subsection guid_gen_sec Random and GUID Generation
- *
- * PJLIB provides facility to create random string
- * (#pj_create_random_string()) or globally unique identifier
- * (see @ref PJ_GUID).
- *
- *
- *
- * @section configure_app_sec Configuring Application to use PJLIB
- *
- * @subsection pjlib_compil_sec Building PJLIB
- *
- * Follow the instructions in \ref pjlib_build_sys_pg to build
- * PJLIB.
- *
- * @subsection pjlib_compil_app_sec Building Applications with PJLIB
- *
- * Use the following settings when building applications with PJLIB.
- *
- * @subsubsection compil_inc_dir_sec Include Search Path
- *
- * Add this to your include search path ($PJLIB is PJLIB root directory):
- * <pre>
- * $PJLIB/include
- * </pre>
- *
- * @subsubsection compil_inc_file_sec Include PJLIB Header
- *
- * To include all PJLIB headers:
- * \verbatim
- #include <pjlib.h>
- \endverbatim
- *
- * Alternatively, you can include individual PJLIB headers like this:
- * \verbatim
- #include <pj/log.h>
- #include <pj/os.h>
- \endverbatim
- *
- *
- * @subsubsection compil_lib_dir_sec Library Path
- *
- * Add this to your library search path:
- * <pre>
- * $PJLIB/lib
- * </pre>
- *
- * Then add the appropriate PJLIB library to your link specification. For
- * example, you would add \c libpj-i386-linux-gcc.a when you're building
- * applications in Linux.
- *
- *
- * @subsection pjlib_fundamentals_sec Principles in Using PJLIB
- *
- * Few things that you \b MUST do when using PJLIB, to make sure that
- * you create trully portable applications.
- *
- * @subsubsection call_pjlib_init_sec Call pj_init()
- *
- * Before you do anything else, call \c pj_init(). This would make sure that
- * PJLIB system is properly set up.
- *
- * @subsubsection no_ansi_subsec Do NOT Use ANSI C
- *
- * Contrary to popular teaching, ANSI C (and LIBC) is not the most portable
- * library in the world, nor it's the most ubiquitous. For example, LIBC
- * is not available in Linux kernel. Also normally LIBC will be excluded
- * from compilation of RTOSes to reduce size.
- *
- * So for maximum portability, do NOT use ANSI C. Do not even try to include
- * any other header files outside <include/pj>. Stick with the functionalities
- * provided by PJLIB.
- *
- *
- * @subsubsection string_rep_subsubsec Use pj_str_t instead of C Strings
- *
- * PJLIB uses pj_str_t instead of normal C strings. You SHOULD follow this
- * convention too. Remember, ANSI string-h is not always available. And
- * PJLIB string is faster!
- *
- * @subsubsection mem_alloc_subsubsec Use Pool for Memory Allocations
- *
- * You MUST NOT use \a malloc() or any other memory allocation functions.
- * Use PJLIB pool instead! It's faster and most portable.
- *
- * @subsection logging_subsubsec Use Logging for Text Display
- *
- * DO NOT use <stdio.h> for text output. Use PJLIB logging instead.
- *
- *
- * @section porting_pjlib_sec0 Porting PJLIB
- *
- * Please see \ref porting_pjlib_pg page on more information to port
- * PJLIB to new target.
- *
- * @section enjoy_sec Enjoy Using PJLIB!
- *
- * We hope that you find PJLIB usefull for your application. If you
- * have any questions, suggestions, critics, bug fixes, or anything
- * else, we would be happy to hear it.
- *
- * Enjoy using PJLIB!

- *
- * @subsection build_sys_install_win32_sec Visual Studio
- *
- * The PJLIB Visual Studio workspace supports the building of PJLIB
- * for Win32 target. Although currently only the Visual Studio 6 Workspace is
- * actively maintained, developers with later version of Visual Studio
- * can easily imports VS6 workspace into their IDE.
- *
- * To start building PJLIB projects with Visual Studio 6 or later, open
- * the \a workspace file in the corresponding \b \c build directory. You have
- * several choices on which \a dsw file to open:
- \verbatim
- $PJPROJECT/build/pjproject.dsw
- $PJPROJECT/pjlib/build/pjlib.dsw
- $PJPROJECT/pjsip/build/pjsip.dsw
- ..etc
- \endverbatim
- *
- * The easiest way is to open <tt>pjproject.dsw</tt> file in \b \c $PJPROJECT/build
- * directory. However this will only build the required projects, not
- * the complete projects. For example, the PJLIB test and samples projects

- * @subsubsection config_site_create_vc_sec Create config_site.h
- *
- * The file <tt><b>$PJPROJECT/pjlib/include/pj/config_site.h</b></tt>
- * is supposed to contain configuration that is specific to your site/target.
- * This file is not part of PJLIB, so you must create it yourself. Normally
- * you just need to create a blank file.
- *
- * The reason why it's not included in PJLIB is so that you would not accidently
- * overwrite your site configuration.
- *
- * If you fail to do this, Visual C will complain with error like:
- *
- * <b>"fatal error C1083: Cannot open include file: 'pj/config_site.h': No such file
- * or directory"</b>.
- *
- * @subsubsection build_vc_subsubsec Build the Projects
- *
- * Just hit the build button!
- *
- *
- * @subsection build_sys_install_unix_sec Make System
- *
- * For other targets, PJLIB provides a rather comprehensive build system
- * that uses GNU \a make (and only GNU \a make will work).
- * Currently, the build system supports building * PJLIB for these targets:
- * - i386/Win32/mingw
- * - i386/Linux
- * - i386/Linux (kernel)
- * - alpha/linux
- * - sparc/SunOS
- * - etc..
- *
- *
- * @subsubsection build_req_sec Requirements
- *
- * In order to use the \c make based build system, you MUST have:
- *
- * - <b>GNU make</b>
- *\n
- * The Makefiles heavily utilize GNU make commands which most likely
- * are not available in other \c make system.
- * - <b>bash</b> shell is recommended.
- *\n
- * Specificly, there is a command <tt>"echo -n"</tt> which may not work
- * in other shells. This command is used when generating dependencies
- * (<tt>make dep</tt>) and it's located in
- * <tt>$PJPROJECT/build/rules.mak</tt>.
- * - <b>ar</b>, <b>ranlib</b> from GNU binutils
- *\n
- * In your system has different <tt>ar</tt> or <tt>ranlib</tt> (e.g. they
- * may have been installed as <tt>gar</tt> and <tt>granlib</tt>), then
- * either you create the relevant symbolic links, <b>or</b> modify
- * <tt>$PJPROJECT/build/cc-gcc.mak</tt> and rename <tt>ar</tt> and
- * <tt>ranlib</tt> to the appropriate names.
- * - <b>gcc</b> to generate dependency.
- *\n
- * Currently the build system uses <tt>"gcc -MM"</tt> to generate build
- * dependencies. If <tt>gcc</tt> is not desired to generate dependency,
- * then either you don't run <tt>make dep</tt>, <b>or</b> edit
- * <tt>$PJPROJECT/build/rules.mak</tt> to calculate dependency using
- * your prefered method. (And let me know when you do so so that I can
- * update the file. :) )
- *
- * @subsubsection build_overview_sec Building the Project
- *
- * Generally, steps required to build the PJLIB are:
- *
- \verbatim
- $ cd /home/user/pjproject # <-- go to $PJPROJECT
- $ vi build.mak # <-- set build target etc
- $ touch pjlib/include/pj/config_site.h
- $ cd pjlib/build # <-- go to projet's build dir
- $ make # <-- build the project
- \endverbatim
- *
- * For other project, \a cd to <tt>build</tt> directory in the project
- * and execute \a make from there.
- *
- * \note For Linux kernel target, there are additional steps required, which
- * will be explained in section \ref linux_kern_target_subsec.
- *
- * @subsubsection build_mak_sec Editing build.mak
- *
- * The \c build.mak file in \c $PJPROJECT root directory is used to
- * specify the build configuration. This file is expected to export
- * the following \a make variables:
- *
- * - <tt><b>MACHINE_NAME</b></tt>
- *\n
- * Target machine/processor, one of: <b>{ i386 | alpha | sparc }</b>.
- *
- * - <tt><b>OS_NAME</b></tt>
- *\n
- * Target operating system, one of: <b>{ win32 | linux |
- * linux-kernel | sunos }</b>.
- *
- * - <tt><b>CC_NAME</b></tt>
- *\n
- * Compiler name: <b>{ gcc | vc }</b>\n
- * (Note that support for Visual C (vc) compiler with the \c make system is
- * experimental, and it will only work when run inside a DOS shell
- * (i.e. <tt>"HOST_NAME=win32"</tt>)).
- *
- * - <tt><b>HOST_NAME</b></tt>
- *\n
- * Build host: <b>{ unix | mingw | win32 }</b>\n
- * (Note: win32 host means a DOS command prompt. Support for this type
- * of development host is experimental).
- *
- * These variables will cause the correct configuration file in
- * \c $PJPROJECT/build directory to be executed by \a make. For
- * example, specifying \c OS_NAME=linux will cause file \c os-linux.mak
- * in \c build directory to be executed. These files contain specific
- * configuration for the option that is selected.
- *
- * For Linux kernel target, you are also required to declare the following
- * variables in this file:
- * - \c KERNEL_DIR: full path of kernel source tree.
- * - \c KERNEL_ARCH: kernel ARCH options (e.g. "ARCH=um"), or leave blank
- * for default.
- * - \c PJPROJECT_DIR: full path of PJPROJECT source tree.
- *
- * Apart from these, there are also additional steps required to build
- * Linux kernel target, which will be explained in \ref linux_kern_target_subsec.
- *
- * @subsubsection build_dir_sec Files in "build" Directory
- *
- * The <tt>*.mak</tt> files in \c $PJPROJECT/build directory are used to specify
- * the configuration for the specified compiler, target machine target
- * operating system, and host options. These files will be executed
- * (included) by \a make during building process, depending on the values
- * specified in <b>$PJPROJECT/build.mak</b> file.
- *
- * Normally you don't need to edit these files, except when you're porting
- * PJLIB to new target.
- *
- * Below are the description of some files in this directory:
- *
- * - <tt>rules.mak</tt>: contains generic rules always included during make.
- * - <tt>cc-gcc.mak</tt>: rules when gcc is used for compiler.
- * - <tt>cc-vc.mak</tt>: rules when MSVC compiler is used.
- * - <tt>host-mingw.mak</tt>: rules for building in mingw host.
- * - <tt>host-unix.mak</tt>: rules for building in Unix/Posix host.
- * - <tt>host-win32.mak</tt>: rules for building in Win32 command console
- * (only valid when VC is used).
- * - <tt>m-i386.mak</tt>: rules when target machine is an i386 processor.
- * - <tt>m-m68k.mak</tt>: rules when target machine is an m68k processor.
- * - <tt>os-linux.mak</tt>: rules when target OS is Linux.
- * - <tt>os-linux-kernel.mak</tt>: rules when PJLIB is to be build as
- * part of Linux kernel.
- * - <tt>os-win32.mak</tt>: rules when target OS is Win32.
- *
- *
- * @subsubsection config_site_create_sec Create config_site.h
- *
- * The file <tt><b>$PJPROJECT/pjlib/include/pj/config_site.h</b></tt>
- * is supposed to contain configuration that is specific to your site/target.
- * This file is not part of PJLIB, so you must create it yourself.
- *
- * The reason why it's not included in PJLIB is so that you would not accidently
- * overwrite your site configuration.
- *
- *
- * @subsubsection invoking_make_sec Invoking make
- *
- * Normally, \a make is invoked in \c build directory under each project.
- * For example, to build PJLIB, you would invoke \a make in
- * \c $PJPROJECT/pjlib/build directory like below:
- *
- \verbatim
- $ cd pjlib/build
- $ make
- \endverbatim
- *
- * Alternatively you may invoke <tt>make</tt> in <tt>$PJPROJECT</tt>
- * directory, to build all projects under that directory (e.g.
- * PJLIB, PJSIP, etc.).
- *
- *
- * @subsubsection linux_kern_target_subsec Linux Kernel Target
- *
- * \note
- * <b>BUILDING APPLICATIONS IN LINUX KERNEL MODE IS A VERY DANGEROUS BUSINESS.
- * YOU MAY CRASH THE WHOLE OF YOUR SYSTEM, CORRUPT YOUR HARDISK, ETC. PJLIB
- * KERNEL MODULES ARE STILL IN EXPERIMENTAL PHASE. DO NOT RUN IT IN PRODUCTION
- * SYSTEMS OR OTHER SYSTEMS WHERE RISK OF LOSS OF DATA IS NOT ACCEPTABLE.
- * YOU HAVE BEEN WARNED.</b>
- *
- * \note
- * <b>User Mode Linux (UML)</b> provides excellent way to experiment with Linux
- * kernel without risking the stability of the host system. See
- * http://user-mode-linux.sourceforge.net for details.
- *
- * \note
- * I only use <b>UML</b> to experiment with PJLIB kernel modules.
- * <b>I wouldn't be so foolish to use my host Linux machine to experiment
- * with this.</b>
- *
- * \note
- * You have been warned.
- *
- * For building PJLIB for Linux kernel target, there are additional steps required.
- * In general, the additional tasks are:
- * - Declare some more variables in <b><tt>build.mak</tt></b> file (this
- * has been explained in \ref build_mak_sec above).
- * - Perform these two small modifications in kernel source tree.
- *
- * There are two small modification need to be applied to the kernel tree.
- *
- * <b>1. Edit <tt>Makefile</tt> in kernel root source tree.</b>
- *
- * Add the following lines at the end of the <tt>Makefile</tt> in your
- * <tt>$KERNEL_SRC</tt> dir:
- \verbatim
-script:
- $(SCRIPT)
- \endverbatim
- *
- * \note Remember to replace spaces with <b>tab</b> in the Makefile.
- *
- * The modification above is needed to capture kernel's \c $CFLAGS and
- * \c $CFLAGS_MODULE which will be used for PJLIB's compilation.
- *
- * <b>2. Add Additional Exports.</b>
- *
- * We need the kernel to export some more symbols for our use. So we declare
- * the additional symbols to be exported in <tt>extra-exports.c</tt> file, and add
- * a this file to be compiled into the kernel:
- *
- * - Copy the file <tt>extra-exports.c</tt> from <tt>pjlib/src/pj</tt>
- * directory to <tt>$KERNEL_SRC/kernel/</tt> directory.
- * - Edit <tt>Makefile</tt> in that directory, and add this line
- * somewhere after the declaration of that variable:
- \verbatim
-obj-y += extra-exports.o
- \endverbatim
- *
- * To illustrate what have been done in your kernel source tree, below
- * is screenshot of my kernel source tree _after_ the modification.
- *
- \verbatim
-[root@vpc-linux linux-2.6.7]# pwd

- * @page porting_pjlib_pg Porting PJLIB
- *
- *
- * @section new_arch_sec Porting to New CPU Architecture
- *
- * Below is step-by-step guide to add support for new CPU architecture.
- * This sample is based on porting to Alpha architecture; however steps for
- * porting to other CPU architectures should be pretty similar.
- *
- * Also note that in this example, the operating system used is <b>Linux</b>.
- * Should you wish to add support for new operating system, then follow
- * the next section \ref porting_os_sec.
- *
- * Step-by-step guide to port to new CPU architecture:
- * - decide the name for the new architecture. In this case, we choose
- * <tt><b>alpha</b></tt>.
- * - edit file <tt>$PJPROJECT/build.mak</tt>, and add new section for
- * the new target:
- * <pre>
- * #
- * # Linux alpha, gcc
- * #
- * export MACHINE_NAME := <b>alpha</b>
- * export OS_NAME := linux
- * export CC_NAME := gcc
- * export HOST_NAME := unix
- * </pre>
- *
- * - create a new file <tt>$PJPROJECT/build/<b>m-alpha</b>.mak</tt>.
- * Alternatively create a copy from other file in this directory.
- * The contents of this file will look something like:
- * <pre>
- * export M_CFLAGS := $(CC_DEF)<b>PJ_M_ALPHA=1</b>
- * export M_CXXFLAGS :=
- * export M_LDFLAGS :=
- * export M_SOURCES :=
- * </pre>
- * - create a new file <tt>$PJPROJECT/pjlib/include/pj/compat/<b>m_alpha.h</b></tt>.
- * Alternatively create a copy from other header file in this directory.
- * The contents of this file will look something like:
- * <pre>
- * #define PJ_HAS_PENTIUM 0
- * #define PJ_IS_LITTLE_ENDIAN 1
- * #define PJ_IS_BIG_ENDIAN 0
- * </pre>
- * - edit <tt>pjlib/include/pj/<b>config.h</b></tt>. Add new processor
- * configuration in this header file, like follows:
- * <pre>
- * ...
- * #elif defined (PJ_M_ALPHA) && PJ_M_ALPHA != 0
- * # include <pj/compat/m_alpha.h>
- * ...
- * </pre>
- * - done. Build PJLIB with:
- * <pre>
- * $ cd $PJPROJECT/pjlib/build
- * $ make dep
- * $ make clean
- * $ make
- * </pre>
- *
- * @section porting_os_sec Porting to New Operating System Target
- *
- * This section will try to give you rough guideline on how to
- * port PJLIB to a new target. As a sample, we give the target a name tag,
- * for example <tt><b>xos</b></tt> (for X OS).
- *
- * @subsection new_compat_os_h_file_sec Create New Compat Header File
- *
- * You'll need to create a new header file
- * <b><tt>include/pj/compat/os_xos.h</tt></b>. You can copy as a
- * template other header file and edit it accordingly.
- *
- * @subsection modify_config_h_file_sec Modify config.h
- *
- * Then modify file <b><tt>include/pj/config.h</tt></b> to include
- * this file accordingly (e.g. when macro <tt><b>PJ_XOS</b></tt> is
- * defined):
- *
- \verbatim
- ...
- #elif defined(PJ_XOS)
- # include <pj/compat/os_xos.h>
- #else
- #...
- \endverbatim
- *
- * @subsection new_target_mak_file_sec Create New Global Make Config File
- *
- * Then you'll need to create global configuration file that
- * is specific for this OS, i.e. <tt><b>os-xos.mak</b></tt> in
- * <tt><b>$PJPROJECT/build</b></tt> directory.
- *
- * At very minimum, the file will normally need to define
- * <tt><b>PJ_XOS=1</b></tt> in the \c CFLAGS section:
- *
- \verbatim
-#
-# $PJPROJECT/build/os-xos.mak:
-#
-export OS_CFLAGS := $(CC_DEF)PJ_XOS=1
-export OS_CXXFLAGS :=
-export OS_LDFLAGS :=
-export OS_SOURCES :=
- \endverbatim
- *
- *
- * @subsection new_target_prj_mak_file_sec Create New Project's Make Config File
- *
- * Then you'll need to create xos-specific configuration file
- * for PJLIB. This file is also named <tt><b>os-xos.mak</b></tt>,
- * but its located in <tt><b>pjlib/build</b></tt> directory.
- * This file will specify source files that are specific to
- * this OS to be included in the build process.
- *
- * Below is a sample:
- \verbatim
-#
-# pjlib/build/os-xos.mak:
-# XOS specific configuration for PJLIB.
-#
-export PJLIB_OBJS += os_core_xos.o \
- os_error_unix.o \
- os_time_ansi.o
-export TEST_OBJS += main.o
-export TARGETS = pjlib pjlib-test
- \endverbatim
- *
- * @subsection new_target_src_sec Create and Edit Source Files
- *
- * You'll normally need to create at least these files:
- * - <tt><b>os_core_xos.c</b></tt>: core OS specific
- * functionality.
- * - <tt><b>os_timestamp_xos.c</b></tt>: how to get timestamp
- * in this OS.
- *
- * Depending on how things are done in your OS, you may need
- * to create these files:
- * - <tt><b>os_error_*.c</b></tt>: how to manipulate
- * OS error codes. Alternatively you may use existing
- * <tt>os_error_unix.c</tt> if the OS has \c errno and
- * \c strerror() function.
- * - <tt><b>ioqueue_*.c</b></tt>: if the OS has specific method
- * to perform asynchronous I/O. Alternatively you may
- * use existing <tt>ioqueue_select.c</tt> if the OS supports
- * \c select() function call.
- * - <tt><b>sock_*.c</b></tt>: if the OS has specific method
- * to perform socket communication. Alternatively you may
- * use existing <tt>sock_bsd.c</tt> if the OS supports
- * BSD socket API, and edit <tt>include/pj/compat/socket.h</tt>
- * file accordingly.
- *
- * You will also need to check various files in
- * <tt><b>include/pj/compat/*.h</b></tt>, to see if they're
- * compatible with your OS.
- *
- * @subsection new_target_build_file_sec Build The Project
- *
- * After basic building blocks have been created for the OS, then
- * the easiest way to see which parts need to be fixed is by building
- * the project and see the error messages.
- *
- * @subsection new_target_edit_vs_new_file_sec Editing Existing Files vs Creating New File
- *
- * When you encounter compatibility errors in PJLIB during porting,
- * you have three options on how to fix the error:
- * - edit the existing <tt>*.c</tt> file, and give it <tt>#ifdef</tt>
- * switch for the new OS, or
- * - edit <tt>include/pj/compat/*.h</tt> instead, or
- * - create a totally new file.
- *
- * Basicly there is no strict rule on which approach is the best
- * to use, however the following guidelines may be used:
- * - if the file is expected to be completely different than
- * any existing file, then perhaps you should create a completely
- * new file. For example, file <tt>os_core_xxx.c</tt> will
- * normally be different for each OS flavour.
- * - if the difference can be localized in <tt>include/compat</tt>
- * header file, and existing <tt>#ifdef</tt> switch is there,
- * then preferably you should edit this <tt>include/compat</tt>
- * header file.
- * - if the existing <tt>*.c</tt> file has <tt>#ifdef</tt> switch,
- * then you may add another <tt>#elif</tt> switch there. This
- * normally is used for behaviors that are not totally
- * different on each platform.
- * - other than that above, use your own judgement on whether
- * to edit the file or create new file etc.

+ *
+ * For other project, \a cd to <tt>build</tt> directory in the project
+ * and execute \a make from there.
+ *
+ * \note For Linux kernel target, there are additional steps required, which
+ * will be explained in section \ref linux_kern_target_subsec.
+ *
+ * @subsubsection build_mak_sec Editing build.mak
+ *
+ * The \c build.mak file in \c $PJPROJECT root directory is used to
+ * specify the build configuration. This file is expected to export
+ * the following \a make variables:
+ *
+ * - <tt><b>MACHINE_NAME</b></tt>
+ *\n
+ * Target machine/processor, one of: <b>{ i386 | alpha | sparc }</b>.
+ *
+ * - <tt><b>OS_NAME</b></tt>
+ *\n
+ * Target operating system, one of: <b>{ win32 | linux |
+ * linux-kernel | sunos }</b>.
+ *
+ * - <tt><b>CC_NAME</b></tt>
+ *\n
+ * Compiler name: <b>{ gcc | vc }</b>\n
+ * (Note that support for Visual C (vc) compiler with the \c make system is
+ * experimental, and it will only work when run inside a DOS shell
+ * (i.e. <tt>"HOST_NAME=win32"</tt>)).
+ *
+ * - <tt><b>HOST_NAME</b></tt>
+ *\n
+ * Build host: <b>{ unix | mingw | win32 }</b>\n
+ * (Note: win32 host means a DOS command prompt. Support for this type
+ * of development host is experimental).
+ *
+ * These variables will cause the correct configuration file in
+ * \c $PJPROJECT/build directory to be executed by \a make. For
+ * example, specifying \c OS_NAME=linux will cause file \c os-linux.mak
+ * in \c build directory to be executed. These files contain specific
+ * configuration for the option that is selected.
+ *
+ * For Linux kernel target, you are also required to declare the following
+ * variables in this file:
+ * - \c KERNEL_DIR: full path of kernel source tree.
+ * - \c KERNEL_ARCH: kernel ARCH options (e.g. "ARCH=um"), or leave blank
+ * for default.
+ * - \c PJPROJECT_DIR: full path of PJPROJECT source tree.
+ *
+ * Apart from these, there are also additional steps required to build
+ * Linux kernel target, which will be explained in \ref linux_kern_target_subsec.
+ *
+ * @subsubsection build_dir_sec Files in "build" Directory
+ *
+ * The <tt>*.mak</tt> files in \c $PJPROJECT/build directory are used to specify
+ * the configuration for the specified compiler, target machine target
+ * operating system, and host options. These files will be executed
+ * (included) by \a make during building process, depending on the values
+ * specified in <b>$PJPROJECT/build.mak</b> file.
+ *
+ * Normally you don't need to edit these files, except when you're porting
+ * PJLIB to new target.
+ *
+ * Below are the description of some files in this directory:
+ *
+ * - <tt>rules.mak</tt>: contains generic rules always included during make.
+ * - <tt>cc-gcc.mak</tt>: rules when gcc is used for compiler.
+ * - <tt>cc-vc.mak</tt>: rules when MSVC compiler is used.
+ * - <tt>host-mingw.mak</tt>: rules for building in mingw host.
+ * - <tt>host-unix.mak</tt>: rules for building in Unix/Posix host.
+ * - <tt>host-win32.mak</tt>: rules for building in Win32 command console
+ * (only valid when VC is used).
+ * - <tt>m-i386.mak</tt>: rules when target machine is an i386 processor.
+ * - <tt>m-m68k.mak</tt>: rules when target machine is an m68k processor.
+ * - <tt>os-linux.mak</tt>: rules when target OS is Linux.
+ * - <tt>os-linux-kernel.mak</tt>: rules when PJLIB is to be build as
+ * part of Linux kernel.
+ * - <tt>os-win32.mak</tt>: rules when target OS is Win32.
+ *
+ *
+ * @subsubsection config_site_create_sec Create config_site.h
+ *
+ * The file <tt><b>$PJPROJECT/pjlib/include/pj/config_site.h</b></tt>
+ * is supposed to contain configuration that is specific to your site/target.
+ * This file is not part of PJLIB, so you must create it yourself.
+ *
+ * The reason why it's not included in PJLIB is so that you would not accidently
+ * overwrite your site configuration.
+ *
+ *
+ * @subsubsection invoking_make_sec Invoking make
+ *
+ * Normally, \a make is invoked in \c build directory under each project.
+ * For example, to build PJLIB, you would invoke \a make in
+ * \c $PJPROJECT/pjlib/build directory like below:
+ *
+ \verbatim
+ $ cd pjlib/build
+ $ make
+ \endverbatim
+ *
+ * Alternatively you may invoke <tt>make</tt> in <tt>$PJPROJECT</tt>
+ * directory, to build all projects under that directory (e.g.
+ * PJLIB, PJSIP, etc.).
+ *
+ *
+ * @subsubsection linux_kern_target_subsec Linux Kernel Target
+ *
+ * \note
+ * <b>BUILDING APPLICATIONS IN LINUX KERNEL MODE IS A VERY DANGEROUS BUSINESS.
+ * YOU MAY CRASH THE WHOLE OF YOUR SYSTEM, CORRUPT YOUR HARDISK, ETC. PJLIB
+ * KERNEL MODULES ARE STILL IN EXPERIMENTAL PHASE. DO NOT RUN IT IN PRODUCTION
+ * SYSTEMS OR OTHER SYSTEMS WHERE RISK OF LOSS OF DATA IS NOT ACCEPTABLE.
+ * YOU HAVE BEEN WARNED.</b>
+ *
+ * \note
+ * <b>User Mode Linux (UML)</b> provides excellent way to experiment with Linux
+ * kernel without risking the stability of the host system. See
+ * http://user-mode-linux.sourceforge.net for details.
+ *
+ * \note
+ * I only use <b>UML</b> to experiment with PJLIB kernel modules.
+ * <b>I wouldn't be so foolish to use my host Linux machine to experiment
+ * with this.</b>
+ *
+ * \note
+ * You have been warned.
+ *
+ * For building PJLIB for Linux kernel target, there are additional steps required.
+ * In general, the additional tasks are:
+ * - Declare some more variables in <b><tt>build.mak</tt></b> file (this
+ * has been explained in \ref build_mak_sec above).
+ * - Perform these two small modifications in kernel source tree.
+ *
+ * There are two small modification need to be applied to the kernel tree.
+ *
+ * <b>1. Edit <tt>Makefile</tt> in kernel root source tree.</b>
+ *
+ * Add the following lines at the end of the <tt>Makefile</tt> in your
+ * <tt>$KERNEL_SRC</tt> dir:
+ \verbatim
+script:
+ $(SCRIPT)
+ \endverbatim
+ *
+ * \note Remember to replace spaces with <b>tab</b> in the Makefile.
+ *
+ * The modification above is needed to capture kernel's \c $CFLAGS and
+ * \c $CFLAGS_MODULE which will be used for PJLIB's compilation.
+ *
+ * <b>2. Add Additional Exports.</b>
+ *
+ * We need the kernel to export some more symbols for our use. So we declare
+ * the additional symbols to be exported in <tt>extra-exports.c</tt> file, and add
+ * a this file to be compiled into the kernel:
+ *
+ * - Copy the file <tt>extra-exports.c</tt> from <tt>pjlib/src/pj</tt>
+ * directory to <tt>$KERNEL_SRC/kernel/</tt> directory.
+ * - Edit <tt>Makefile</tt> in that directory, and add this line
+ * somewhere after the declaration of that variable:
+ \verbatim
+obj-y += extra-exports.o
+ \endverbatim
+ *
+ * To illustrate what have been done in your kernel source tree, below
+ * is screenshot of my kernel source tree _after_ the modification.
+ *
+ \verbatim

+/**
+ * @page porting_pjlib_pg Porting PJLIB
+ *
+ *
+ * @section new_arch_sec Porting to New CPU Architecture
+ *
+ * Below is step-by-step guide to add support for new CPU architecture.
+ * This sample is based on porting to Alpha architecture; however steps for
+ * porting to other CPU architectures should be pretty similar.
+ *
+ * Also note that in this example, the operating system used is <b>Linux</b>.
+ * Should you wish to add support for new operating system, then follow
+ * the next section \ref porting_os_sec.
+ *
+ * Step-by-step guide to port to new CPU architecture:
+ * - decide the name for the new architecture. In this case, we choose
+ * <tt><b>alpha</b></tt>.
+ * - edit file <tt>$PJPROJECT/build.mak</tt>, and add new section for
+ * the new target:
+ * <pre>
+ * #
+ * # Linux alpha, gcc
+ * #
+ * export MACHINE_NAME := <b>alpha</b>
+ * export OS_NAME := linux
+ * export CC_NAME := gcc
+ * export HOST_NAME := unix
+ * </pre>
+ *
+ * - create a new file <tt>$PJPROJECT/build/<b>m-alpha</b>.mak</tt>.
+ * Alternatively create a copy from other file in this directory.
+ * The contents of this file will look something like:
+ * <pre>
+ * export M_CFLAGS := $(CC_DEF)<b>PJ_M_ALPHA=1</b>
+ * export M_CXXFLAGS :=
+ * export M_LDFLAGS :=
+ * export M_SOURCES :=
+ * </pre>
+ * - create a new file <tt>$PJPROJECT/pjlib/include/pj/compat/<b>m_alpha.h</b></tt>.
+ * Alternatively create a copy from other header file in this directory.
+ * The contents of this file will look something like:
+ * <pre>
+ * #define PJ_HAS_PENTIUM 0
+ * #define PJ_IS_LITTLE_ENDIAN 1
+ * #define PJ_IS_BIG_ENDIAN 0
+ * </pre>
+ * - edit <tt>pjlib/include/pj/<b>config.h</b></tt>. Add new processor
+ * configuration in this header file, like follows:
+ * <pre>
+ * ...
+ * #elif defined (PJ_M_ALPHA) && PJ_M_ALPHA != 0
+ * # include <pj/compat/m_alpha.h>
+ * ...
+ * </pre>
+ * - done. Build PJLIB with:
+ * <pre>
+ * $ cd $PJPROJECT/pjlib/build
+ * $ make dep
+ * $ make clean
+ * $ make
+ * </pre>
+ *
+ * @section porting_os_sec Porting to New Operating System Target
+ *
+ * This section will try to give you rough guideline on how to
+ * port PJLIB to a new target. As a sample, we give the target a name tag,
+ * for example <tt><b>xos</b></tt> (for X OS).
+ *
+ * @subsection new_compat_os_h_file_sec Create New Compat Header File
+ *
+ * You'll need to create a new header file
+ * <b><tt>include/pj/compat/os_xos.h</tt></b>. You can copy as a
+ * template other header file and edit it accordingly.
+ *
+ * @subsection modify_config_h_file_sec Modify config.h
+ *
+ * Then modify file <b><tt>include/pj/config.h</tt></b> to include
+ * this file accordingly (e.g. when macro <tt><b>PJ_XOS</b></tt> is
+ * defined):
+ *
+ \verbatim
+ ...
+ #elif defined(PJ_XOS)
+ # include <pj/compat/os_xos.h>
+ #else
+ #...
+ \endverbatim
+ *
+ * @subsection new_target_mak_file_sec Create New Global Make Config File
+ *
+ * Then you'll need to create global configuration file that
+ * is specific for this OS, i.e. <tt><b>os-xos.mak</b></tt> in
+ * <tt><b>$PJPROJECT/build</b></tt> directory.
+ *
+ * At very minimum, the file will normally need to define
+ * <tt><b>PJ_XOS=1</b></tt> in the \c CFLAGS section:
+ *
+ \verbatim
+#
+# $PJPROJECT/build/os-xos.mak:
+#
+export OS_CFLAGS := $(CC_DEF)PJ_XOS=1
+export OS_CXXFLAGS :=
+export OS_LDFLAGS :=
+export OS_SOURCES :=
+ \endverbatim
+ *
+ *
+ * @subsection new_target_prj_mak_file_sec Create New Project's Make Config File
+ *
+ * Then you'll need to create xos-specific configuration file
+ * for PJLIB. This file is also named <tt><b>os-xos.mak</b></tt>,
+ * but its located in <tt><b>pjlib/build</b></tt> directory.
+ * This file will specify source files that are specific to
+ * this OS to be included in the build process.
+ *
+ * Below is a sample:
+ \verbatim
+#
+# pjlib/build/os-xos.mak:
+# XOS specific configuration for PJLIB.
+#
+export PJLIB_OBJS += os_core_xos.o \
+ os_error_unix.o \
+ os_time_ansi.o
+export TEST_OBJS += main.o
+export TARGETS = pjlib pjlib-test
+ \endverbatim
+ *
+ * @subsection new_target_src_sec Create and Edit Source Files
+ *
+ * You'll normally need to create at least these files:
+ * - <tt><b>os_core_xos.c</b></tt>: core OS specific
+ * functionality.
+ * - <tt><b>os_timestamp_xos.c</b></tt>: how to get timestamp
+ * in this OS.
+ *
+ * Depending on how things are done in your OS, you may need
+ * to create these files:
+ * - <tt><b>os_error_*.c</b></tt>: how to manipulate
+ * OS error codes. Alternatively you may use existing
+ * <tt>os_error_unix.c</tt> if the OS has \c errno and
+ * \c strerror() function.
+ * - <tt><b>ioqueue_*.c</b></tt>: if the OS has specific method
+ * to perform asynchronous I/O. Alternatively you may
+ * use existing <tt>ioqueue_select.c</tt> if the OS supports
+ * \c select() function call.
+ * - <tt><b>sock_*.c</b></tt>: if the OS has specific method
+ * to perform socket communication. Alternatively you may
+ * use existing <tt>sock_bsd.c</tt> if the OS supports
+ * BSD socket API, and edit <tt>include/pj/compat/socket.h</tt>
+ * file accordingly.
+ *
+ * You will also need to check various files in
+ * <tt><b>include/pj/compat/*.h</b></tt>, to see if they're
+ * compatible with your OS.
+ *
+ * @subsection new_target_build_file_sec Build The Project
+ *
+ * After basic building blocks have been created for the OS, then
+ * the easiest way to see which parts need to be fixed is by building
+ * the project and see the error messages.
+ *
+ * @subsection new_target_edit_vs_new_file_sec Editing Existing Files vs Creating New File
+ *
+ * When you encounter compatibility errors in PJLIB during porting,
+ * you have three options on how to fix the error:
+ * - edit the existing <tt>*.c</tt> file, and give it <tt>#ifdef</tt>
+ * switch for the new OS, or
+ * - edit <tt>include/pj/compat/*.h</tt> instead, or
+ * - create a totally new file.
+ *
+ * Basicly there is no strict rule on which approach is the best
+ * to use, however the following guidelines may be used:
+ * - if the file is expected to be completely different than
+ * any existing file, then perhaps you should create a completely
+ * new file. For example, file <tt>os_core_xxx.c</tt> will
+ * normally be different for each OS flavour.
+ * - if the difference can be localized in <tt>include/compat</tt>
+ * header file, and existing <tt>#ifdef</tt> switch is there,
+ * then preferably you should edit this <tt>include/compat</tt>
+ * header file.
+ * - if the existing <tt>*.c</tt> file has <tt>#ifdef</tt> switch,
+ * then you may add another <tt>#elif</tt> switch there. This
+ * normally is used for behaviors that are not totally
+ * different on each platform.
+ * - other than that above, use your own judgement on whether
+ * to edit the file or create new file etc.

- *
- * For the impatient, take a look at some examples:
- * - @ref page_pjlib_samples_except_c
- * - @ref page_pjlib_exception_test
- *
- * \section pj_except_except Exception Handling
- *
- * This module provides exception handling syntactically similar to C++ in
- * C language. The underlying mechanism use setjmp() and longjmp(), and since
- * these constructs are ANSI standard, the mechanism here should be available
- * on most platforms/compilers which are ANSI compliant.
- *
- * If ANSI libc is not available, then setjmp()/longjmp() implementation will
- * be provided. See <pj/compat/setjmp.h> for compatibility.
- *
- * The exception handling mechanism is completely thread safe, so the exception
- * thrown by one thread will not interfere with other thread.
- *
- * CAVEATS:
- * - unlike C++ exception, the scheme here won't call destructors of local
- * objects if exception is thrown. Care must be taken when a function
- * hold some resorce such as pool or mutex etc.
- * - You CAN NOT make nested exception in one single function without using
- * a nested PJ_USE_EXCEPTION.
- * - Exceptions will always be caught by the first handle (unlike C++ where
- * exception is only caught if the type matches.
- *
- * The exception handling constructs are similar to C++. The blocks will be
- * constructed similar to the following sample:
- *
- * \verbatim
- #define NO_MEMORY 1
- #define SYNTAX_ERROR 2
-
- int main()
- {
- PJ_USE_EXCEPTION; // declare local exception stack.
-
- PJ_TRY {
- ...// do something..
- }
- PJ_CATCH(NO_MEMORY) {
- ... // handle exception 1
- }
- PJ_CATCH(SYNTAX_ERROR) {
- ... // handle exception 2
- }
- PJ_DEFAULT {
- ... // handle other exceptions.
- }
- PJ_END;
- }
- \endverbatim
- *
- * The above sample uses hard coded exception ID. It is @b strongly
- * recommended that applications request a unique exception ID instead
- * of hard coded value like above.
- *
- * \section pj_except_reg Exception ID Allocation
- *
- * To ensure that exception ID (number) are used consistently and to
- * prevent ID collisions in an application, it is strongly suggested that
- * applications allocate an exception ID for each possible exception
- * type. As a bonus of this process, the application can identify
- * the name of the exception when the particular exception is thrown.
- *
- * Exception ID management are performed with the following APIs:
- * - #pj_exception_id_alloc().
- * - #pj_exception_id_free().
- * - #pj_exception_id_name().
- *
- *
- * PJLIB itself automatically allocates one exception id, i.e.
- * #PJ_NO_MEMORY_EXCEPTION which is declared in <pj/pool.h>. This exception
- * ID is raised by default pool policy when it fails to allocate memory.
- *
- * \section PJ_EX_KEYWORDS Keywords
- *
- * \subsection PJ_THROW PJ_THROW(expression)
- * Throw an exception. The expression thrown is an integer as the result of
- * the \a expression. This keyword can be specified anywhere within the
- * program.
- *
- * \subsection PJ_USE_EXCEPTION PJ_USE_EXCEPTION
- * Specify this in the variable definition section of the function block
- * (or any blocks) to specify that the block has \a PJ_TRY/PJ_CATCH exception
- * block.
- * Actually, this is just a macro to declare local variable which is used to
- * push the exception state to the exception stack.
- *
- * \subsection PJ_TRY PJ_TRY
- * The \a PJ_TRY keyword is typically followed by a block. If an exception is
- * thrown in this block, then the execution will resume to the \a PJ_CATCH
- * handler.
- *
- * \subsection PJ_CATCH PJ_CATCH(expression)
- * The \a PJ_CATCH is normally followed by a block. This block will be executed
- * if the exception being thrown is equal to the expression specified in the
- * \a PJ_CATCH.
- *
- * \subsection PJ_DEFAULT PJ_DEFAULT
- * The \a PJ_DEFAULT keyword is normally followed by a block. This block will
- * be executed if the exception being thrown doesn't match any of the \a
- * PJ_CATCH specification. The \a PJ_DEFAULT block \b MUST be placed as the
- * last block of the handlers.
- *
- * \subsection PJ_END PJ_END
- * Specify this keyword to mark the end of \a PJ_TRY / \a PJ_CATCH blocks.
- *
- * \subsection PJ_GET_EXCEPTION PJ_GET_EXCEPTION(void)
- * Get the last exception thrown. This macro is normally called inside the
- * \a PJ_CATCH or \a PJ_DEFAULT block, altough it can be used anywhere where
- * the \a PJ_USE_EXCEPTION definition is in scope.

- * @defgroup PJ_IOQUEUE I/O Event Dispatching Queue
- * @ingroup PJ_IO
- * @{
- *
- * I/O Queue provides API for performing asynchronous I/O operations. It
- * conforms to proactor pattern, which allows application to submit an
- * asynchronous operation and to be notified later when the operation has
- * completed.
- *
- * The I/O Queue can work on both socket and file descriptors. For
- * asynchronous file operations however, one must make sure that the correct
- * file I/O back-end is used, because not all file I/O back-end can be
- * used with the ioqueue. Please see \ref PJ_FILE_IO for more details.
- *
- * The framework works natively in platforms where asynchronous operation API
- * exists, such as in Windows NT with IoCompletionPort/IOCP. In other
- * platforms, the I/O queue abstracts the operating system's event poll API
- * to provide semantics similar to IoCompletionPort with minimal penalties
- * (i.e. per ioqueue and per handle mutex protection).
- *
- * The I/O queue provides more than just unified abstraction. It also:
- * - makes sure that the operation uses the most effective way to utilize
- * the underlying mechanism, to achieve the maximum theoritical
- * throughput possible on a given platform.
- * - choose the most efficient mechanism for event polling on a given
- * platform.
- *
- * Currently, the I/O Queue is implemented using:
- * - <tt><b>select()</b></tt>, as the common denominator, but the least
- * efficient. Also the number of descriptor is limited to
- * \c PJ_IOQUEUE_MAX_HANDLES (which by default is 64).
- * - <tt><b>/dev/epoll</b></tt> on Linux (user mode and kernel mode),
- * a much faster replacement for select() on Linux (and more importantly
- * doesn't have limitation on number of descriptors).
- * - <b>I/O Completion ports</b> on Windows NT/2000/XP, which is the most
- * efficient way to dispatch events in Windows NT based OSes, and most
- * importantly, it doesn't have the limit on how many handles to monitor.
- * And it works with files (not only sockets) as well.
- *
- *
- * \section pj_ioqueue_concurrency_sec Concurrency Rules
- *
- * The items below describe rules that must be obeyed when using the I/O
- * queue, with regard to concurrency:
- * - simultaneous operations (by different threads) to different key is safe.
- * - simultaneous operations to the same key is also safe, except
- * <b>unregistration</b>, which is described below.
- * - <b>care must be taken when unregistering a key</b> from the
- * ioqueue. Application must take care that when one thread is issuing
- * an unregistration, other thread is not simultaneously invoking an
- * operation <b>to the same key</b>.
- *\n
- * This happens because the ioqueue functions are working with a pointer
- * to the key, and there is a possible race condition where the pointer
- * has been rendered invalid by other threads before the ioqueue has a
- * chance to acquire mutex on it.
- *
- * \section pj_ioqeuue_examples_sec Examples

- * @defgroup PJ_POOL_GROUP Memory Pool Management
- * @ingroup PJ
- * @brief
- * Memory pool management provides API to allocate and deallocate memory from
- * memory pool and to manage and establish policy for pool creation and
- * destruction in pool factory.
- *
- * \section PJ_POOL_FACTORY_SEC Pool Factory
- * See: \ref PJ_POOL_FACTORY "Pool Factory"
- *
- * A memory pool must be created through a factory. A factory not only provides
- * generic interface functions to create and release pool, but also provides
- * strategy to manage the life time of pools. One sample implementation,
- * \a pj_caching_pool, can be set to keep the pools released by application for
- * future use as long as the total memory is below the limit.
- *
- * The pool factory interface declared in PJLIB is designed to be extensible.
- * Application can define its own strategy by creating it's own pool factory
- * implementation, and this strategy can be used even by existing library
- * without recompilation.
- *
- *
- * \section PJ_POOL_POLICY_SEC Pool Factory Policy
- * See: \ref PJ_POOL_FACTORY "Pool Factory Policy"
- *
- * A pool factory only defines functions to create and release pool and how
- * to manage pools, but the rest of the functionalities are controlled by
- * policy. A pool policy defines:
- * - how memory block is allocated and deallocated (the default implementation
- * allocates and deallocate memory by calling malloc() and free()).
- * - callback to be called when memory allocation inside a pool fails (the
- * default implementation will throw PJ_NO_MEMORY_EXCEPTION exception).
- * - concurrency when creating and releasing pool from/to the factory.
- *
- * A pool factory can be given different policy during creation to make
- * it behave differently. For example, caching pool factory can be configured
- * to allocate and deallocate from a static/contiguous/preallocated memory
- * instead of using malloc()/free().
- *
- * What strategy/factory and what policy to use is not defined by PJLIB, but
- * instead is left to application to make use whichever is most efficient for
- * itself.
- *
- *
- * \section PJ_POOL_POOL_SEC The Pool
- * See: \ref PJ_POOL "Pool"
- *
- * The memory pool is an opaque object created by pool factory.
- * Application uses this object to request a memory chunk, by calling
- * #pj_pool_alloc or #pj_pool_calloc. When the application has finished using
- * the pool, it must call #pj_pool_release to free all the chunks previously
- * allocated and release the pool back to the factory.
- *
- * \section PJ_POOL_THREADING_SEC More on Threading Policies:
- * - By design, memory allocation from a pool is not thread safe. We assumed
- * that a pool will be owned by an object, and thread safety should be
- * handled by that object. Thus these functions are not thread safe:
- * - #pj_pool_alloc,
- * - #pj_pool_calloc,
- * - and other pool statistic functions.
- * - Threading in the pool factory is decided by the policy set for the
- * factory when it was created.
- *
- * \section PJ_POOL_EXAMPLES_SEC Examples
- *
- * For some sample codes on how to use the pool, please see:
- * - @ref page_pjlib_pool_test

- * @brief
- * A memory pool is initialized with an initial amount of memory, which is
- * called a block. Pool can be configured to dynamically allocate more memory
- * blocks when it runs out of memory. Subsequent memory allocations by user
- * will use up portions of these block.
- * The pool doesn't keep track of individual memory allocations
- * by user, and the user doesn't have to free these indidual allocations. This
- * makes memory allocation simple and very fast. All the memory allocated from
- * the pool will be destroyed when the pool itself is destroyed.

+ * @ingroup PJ
+ * @brief
+ * Memory pool management provides API to allocate and deallocate memory from
+ * memory pool and to manage and establish policy for pool creation and
+ * destruction in pool factory.
+ *
+ * \section PJ_POOL_FACTORY_SEC Pool Factory
+ * See: \ref PJ_POOL_FACTORY "Pool Factory"
+ *
+ * A memory pool must be created through a factory. A factory not only provides
+ * generic interface functions to create and release pool, but also provides
+ * strategy to manage the life time of pools. One sample implementation,
+ * \a pj_caching_pool, can be set to keep the pools released by application for
+ * future use as long as the total memory is below the limit.
+ *
+ * The pool factory interface declared in PJLIB is designed to be extensible.
+ * Application can define its own strategy by creating it's own pool factory
+ * implementation, and this strategy can be used even by existing library
+ * without recompilation.
+ *
+ *
+ * \section PJ_POOL_POLICY_SEC Pool Factory Policy
+ * See: \ref PJ_POOL_FACTORY "Pool Factory Policy"
+ *
+ * A pool factory only defines functions to create and release pool and how
+ * to manage pools, but the rest of the functionalities are controlled by
+ * policy. A pool policy defines:
+ * - how memory block is allocated and deallocated (the default implementation
+ * allocates and deallocate memory by calling malloc() and free()).
+ * - callback to be called when memory allocation inside a pool fails (the
+ * default implementation will throw PJ_NO_MEMORY_EXCEPTION exception).
+ * - concurrency when creating and releasing pool from/to the factory.
+ *
+ * A pool factory can be given different policy during creation to make
+ * it behave differently. For example, caching pool factory can be configured
+ * to allocate and deallocate from a static/contiguous/preallocated memory
+ * instead of using malloc()/free().
+ *
+ * What strategy/factory and what policy to use is not defined by PJLIB, but
+ * instead is left to application to make use whichever is most efficient for
+ * itself.
+ *
+ *
+ * \section PJ_POOL_POOL_SEC The Pool
+ * See: \ref PJ_POOL "Pool"
+ *
+ * The memory pool is an opaque object created by pool factory.
+ * Application uses this object to request a memory chunk, by calling
+ * #pj_pool_alloc or #pj_pool_calloc. When the application has finished using
+ * the pool, it must call #pj_pool_release to free all the chunks previously
+ * allocated and release the pool back to the factory.
+ *
+ * \section PJ_POOL_THREADING_SEC More on Threading Policies:
+ * - By design, memory allocation from a pool is not thread safe. We assumed
+ * that a pool will be owned by an object, and thread safety should be
+ * handled by that object. Thus these functions are not thread safe:
+ * - #pj_pool_alloc,
+ * - #pj_pool_calloc,
+ * - and other pool statistic functions.
+ * - Threading in the pool factory is decided by the policy set for the
+ * factory when it was created.
+ *
+ * \section PJ_POOL_EXAMPLES_SEC Examples
+ *
+ * For some sample codes on how to use the pool, please see:
+ * - @ref page_pjlib_pool_test
+ */

+ * @brief
+ * A memory pool is initialized with an initial amount of memory, which is
+ * called a block. Pool can be configured to dynamically allocate more memory
+ * blocks when it runs out of memory. Subsequent memory allocations by user
+ * will use up portions of these block.
+ * The pool doesn't keep track of individual memory allocations
+ * by user, and the user doesn't have to free these indidual allocations. This

+ * the pool will be destroyed when the pool itself is destroyed.

+ * @{
+ *
+ * The PJLIB socket abstraction layer is a thin and very portable abstraction
+ * for socket API. It provides API similar to BSD socket API. The abstraction
+ * is needed because BSD socket API is not always available on all platforms,
+ * therefore it wouldn't be possible to create a trully portable network
+ * programs unless we provide such abstraction.
+ *
+ * Applications can use this API directly in their application, just
+ * as they would when using traditional BSD socket API, provided they
+ * call #pj_init() first.
+ *
+ * \section pj_sock_examples_sec Examples
+ *
+ * For some examples on how to use the socket API, please see:

- * (I even left most of the comments in the original source).
- *
- * To quote the original quote in ACE_Timer_Heap_T class:
- *
- * This implementation uses a heap-based callout queue of

- * scheduling, canceling, and expiring timers is O(log N) (where
- * N is the total number of timers). In addition, we can also
- * preallocate as many \a ACE_Timer_Nodes as there are slots in

- * dynamic memory allocation, which is important for real-time
- * systems.
