NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int  pcre_get_substring(const  char *subject, int *ovec-
       tor,
            int stringcount, int stringnumber,
            const char **stringptr);

DESCRIPTION

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

         subject         Subject  that  has  been  successfully
       matched
         ovector       Offset vector that pcre_exec() used
         stringcount   Value returned by pcre_exec()
         stringnumber  Number of the required substring
         stringptr     Where to put the string pointer

       The memory in which the substring is placed is  obtained
       by  calling  pcre_malloc(). The yield of the function is
       the length of the substring, PCRE_ERROR_NOMEMORY if suf-
       ficient    memory    could    not    be   obtained,   or
       PCRE_ERROR_NOSUBSTRING if the string number 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.
