Synopsis

#include <pcre.h>
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 length 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 native API in the pcreapi(3) page and a description of the POSIX API in the pcreposix(3) page.
