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 API in the pcreapi page.
