NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int pcre_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

         PCRE_CONFIG_JITTARGET     String containing information about the
                                     target architecture for the JIT compiler,
                                     or NULL if there is no JIT support

         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.
