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 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 native API in the pcreapi page and a
       description of the POSIX API in the pcreposix page.
