NAME

       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       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 memory in which the substring is  placed  is  obtained  by  calling
       pcre_malloc().  The  yield  of  the  function is the length of the sub-
       string, 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 native API in the pcreapi
       page and a description of the POSIX API in the pcreposix page.
