PCRE_CONFIG(3) Library Functions Manual PCRE_CONFIG(3) NAME PCRE - Perl-compatible regular expressions SYNOPSIS #include <pcre.h> int pcre_config(int what, void *where); int pcre16_config(int what, void *where); int pcre32_config(int what, void *where); DESCRIPTION This function makes it possible for a client program to find out which optional features are available in the version of the PCRE library it is using. The arguments are as follows: what A code specifying what information is required where Points to where to put the data The where argument must point to an integer variable, except for PCRE_CONFIG_MATCH_LIMIT, PCRE_CONFIG_MATCH_LIMIT_RECURSION, and PCRE_CONFIG_PARENS_LIMIT, when it must point to an unsigned long inte- ger, and for PCRE_CONFIG_JITTARGET, when it must point to a const char*. The available codes are: PCRE_CONFIG_JIT Availability of just-in-time compiler support (1=yes 0=no) PCRE_CONFIG_JITTARGET String containing information about the target architecture for the JIT compiler, or NULL if there is no JIT support PCRE_CONFIG_LINK_SIZE Internal link size: 2, 3, or 4 PCRE_CONFIG_PARENS_LIMIT Parentheses nesting limit PCRE_CONFIG_MATCH_LIMIT Internal resource limit PCRE_CONFIG_MATCH_LIMIT_RECURSION Internal recursion depth limit PCRE_CONFIG_NEWLINE Value of the default newline sequence: 13 (0x000d) for CR 10 (0x000a) for LF 3338 (0x0d0a) for CRLF -2 for ANYCRLF -1 for ANY PCRE_CONFIG_BSR Indicates what \R matches by default: 0 all Unicode line endings 1 CR, LF, or CRLF only PCRE_CONFIG_POSIX_MALLOC_THRESHOLD Threshold of return slots, above which malloc() is used by the POSIX API PCRE_CONFIG_STACKRECURSE Recursion implementation (1=stack 0=heap) PCRE_CONFIG_UTF16 Availability of UTF-16 support (1=yes 0=no); option for pcre16_config() PCRE_CONFIG_UTF32 Availability of UTF-32 support (1=yes 0=no); option for pcre32_config() PCRE_CONFIG_UTF8 Availability of UTF-8 support (1=yes 0=no); option for pcre_config() PCRE_CONFIG_UNICODE_PROPERTIES Availability of Unicode property support (1=yes 0=no) The function yields 0 on success or PCRE_ERROR_BADOPTION otherwise. That error is also given if PCRE_CONFIG_UTF16 or PCRE_CONFIG_UTF32 is passed to pcre_config(), if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF32 is passed to pcre16_config(), or if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF16 is passed to pcre32_config(). There is a complete description of the PCRE native API in the pcreapi page and a description of the POSIX API in the pcreposix page.
