SYNOPSIS
 

#include &#60;pcre.h&#62;


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:
<pre>
 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
</pre>
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.
