       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #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);

DESCRIPTION

       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]_exec() used
         stringcount   Value returned by pcre[16]_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]_malloc().  The
       convenience function pcre[16]_free_substring() 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.
