SYNOPSIS
 

#include &#60;pcre.h&#62;


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:
<pre>
 what A code specifying what information is required
 where Points to where to put the data
</pre>
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 integer,
and for PCRE_CONFIG_JITTARGET, when it must point to a const char*.
The available codes are:
<pre>
 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)
</pre>
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().
