NAME

       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int pcre_copy_named_substring(const pcre *code,
            const char *subject, int *ovector,
            int stringcount, const char *stringname,
            char *buffer, int buffersize);

DESCRIPTION

       This  is  a  convenience  function for extracting a captured substring,
       identified by name, into a given buffer. The arguments are:

         code          Pattern that was successfully matched
         subject       Subject that has been successfully matched
         ovector       Offset vector that pcre_exec() used
         stringcount   Value returned by pcre_exec()
         stringname    Name of the required substring
         buffer        Buffer to receive the string
         buffersize    Size of buffer

       The yield is the length of the substring,  PCRE_ERROR_NOMEMORY  if  the
       buffer  was  too small, or PCRE_ERROR_NOSUBSTRING if the string name 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.
