#ifndef __WXDEBUG__
#define __WXDEBUG__

// This library provides fairly straight forward debugging functionality, this
// is split into two main sections. The first is assertion handling, there are
// three types of assertions provided here. The most commonly used one is the
// ASSERT(condition) macro which will pop up a message box including the file
// and line number if the condition evaluates to FALSE. Then there is the
// EXECUTE_ASSERT macro which is the same as ASSERT except the condition will
// still be executed in NON debug builds. The final type of assertion is the
// KASSERT macro which is more suitable for pure (perhaps kernel) filters as
// the condition is printed onto the debugger rather than in a message box.
//
// The other part of the debug module facilties is general purpose logging.
// This is accessed by calling DbgLog(). The function takes a type and level
// field which define the type of informational string you are presenting and
// it's relative importance. The type field can be a combination (one or more)
// of LOG_TIMING, LOG_TRACE, LOG_MEMORY, LOG_LOCKING and LOG_ERROR. The level
// is a DWORD value where zero defines highest important. Use of zero as the
// debug logging level is to be encouraged ONLY for major errors or events as
// they will ALWAYS be displayed on the debugger. Other debug output has it's
// level matched against the current debug output level stored in the registry
// for this module and if less than the current setting it will be displayed.
//
// Each module or executable has it's own debug output level for each of the
// five types. These are read in when the DbgInitialise function is called
// for DLLs linking to STRMBASE.LIB this is done automatically when the DLL
// is loaded, executables must call it explicitely with the module instance
// handle given to them through the WINMAIN entry point. An executable must
// also call DbgTerminate when they have finished to clean up the resources
// the debug library uses, once again this is done automatically for DLLs

// These are the five different categories of logging information
