NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include 

       int pcre_get_substring(const char *subject, int *ovector,
            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    yield    is    the   length   of   the   substring,
       PCRE_ERROR_NOMEMORY if  sufficient  memory  could  not  be
       obtained,  or  PCRE_ERROR_NOSUBSTRING if the string number
       is invalid.

       There is a complete description of the  PCRE  API  in  the
       pcreapi page.
