PCRE_CONFIG(3)		   Library Functions Manual		PCRE_CONFIG(3)

       PCRE - Perl-compatible regular expressions

       #include	<pcre.h>

       int pcre_config(int what, void *where);

       int pcre16_config(int what, void	*where);

       int pcre32_config(int what, void	*where);

       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_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
				   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
				   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()
				   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.
