SYNOPSIS

       #include 

       int pcre_copy_substring(const char *subject, int *ovector,
            int stringcount, int stringnumber, char *buffer,
            int buffersize);


DESCRIPTION

       This is a convenience function for extracting  a  captured
       substring into a given buffer. 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
         buffer        Buffer to receive the string
         buffersize    Size of buffer

       The yield is the legnth of the string, PCRE_ERROR_NOMEMORY
       if  the buffer was too small, or PCRE_ERROR_NOSUBSTRING if
       the string number is invalid.

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