       PCRE - Perl-compatible regular expressions


       #include <pcre.h>

       int pcre_get_named_substring(const pcre *code,
	    const char *subject, int *ovector,
	    int stringcount, const char *stringname,
	    const char **stringptr);

       int pcre16_get_named_substring(const pcre16 *code,
	    PCRE_SPTR16 subject, int *ovector,
	    int stringcount, PCRE_SPTR16 stringname,
	    PCRE_SPTR16 *stringptr);

       int pcre32_get_named_substring(const pcre32 *code,
	    PCRE_SPTR32 subject, int *ovector,
	    int stringcount, PCRE_SPTR32 stringname,
	    PCRE_SPTR32 *stringptr);


       This  is	 a convenience function for extracting a captured substring by
       name. The arguments are:

	 code	       Compiled pattern
	 subject       Subject that has been successfully matched
	 ovector       Offset vector that pcre[16|32]_exec() used
	 stringcount   Value returned by pcre[16|32]_exec()
	 stringname    Name of the required substring
	 stringptr     Where to put the string pointer

       The memory in which the substring is  placed  is	 obtained  by  calling
       pcre[16|32]_malloc().  The  convenience	function pcre[16|32]_free_sub‐
       string() can be used to free it when it is no longer needed. The	 yield
       of   the	  function   is	  the	length	of  the	 extracted  substring,
       PCRE_ERROR_NOMEMORY if sufficient memory	 could	not  be	 obtained,  or
       PCRE_ERROR_NOSUBSTRING if the string name is invalid.

       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.
