| 27 | <P> |
| 28 | This function makes it possible for a client program to find out which optional |
| 29 | features are available in the version of the PCRE library it is using. The |
| 30 | arguments are as follows: |
| 31 | <pre> |
| 32 | <i>what</i> A code specifying what information is required |
| 33 | <i>where</i> Points to where to put the data |
| 34 | </pre> |
| 35 | The <i>where</i> argument must point to an integer variable, except for |
| 36 | PCRE_CONFIG_MATCH_LIMIT and PCRE_CONFIG_MATCH_LIMIT_RECURSION, when it must |
| 37 | point to an unsigned long integer. The available codes are: |
| 38 | <pre> |
| 39 | PCRE_CONFIG_JIT Availability of just-in-time compiler |
| 40 | support (1=yes 0=no) |
| 41 | PCRE_CONFIG_LINK_SIZE Internal link size: 2, 3, or 4 |
| 42 | PCRE_CONFIG_MATCH_LIMIT Internal resource limit |
| 43 | PCRE_CONFIG_MATCH_LIMIT_RECURSION |
| 44 | Internal recursion depth limit |
| 45 | PCRE_CONFIG_NEWLINE Value of the default newline sequence: |
| 46 | 13 (0x000d) for CR |
| 47 | 10 (0x000a) for LF |
| 48 | 3338 (0x0d0a) for CRLF |
| 49 | -2 for ANYCRLF |
| 50 | -1 for ANY |
| 51 | PCRE_CONFIG_BSR Indicates what \R matches by default: |
| 52 | 0 all Unicode line endings |
| 53 | 1 CR, LF, or CRLF only |
| 54 | PCRE_CONFIG_POSIX_MALLOC_THRESHOLD |
| 55 | Threshold of return slots, above which |
| 56 | <b>malloc()</b> is used by the POSIX API |
| 57 | PCRE_CONFIG_STACKRECURSE Recursion implementation (1=stack 0=heap) |
| 58 | PCRE_CONFIG_UTF8 Availability of UTF-8 support (1=yes 0=no) |
| 59 | PCRE_CONFIG_UNICODE_PROPERTIES |
| 60 | Availability of Unicode property support |
| 61 | (1=yes 0=no) |
| 62 | </pre> |
| 63 | The function yields 0 on success or PCRE_ERROR_BADOPTION otherwise. |
