DESCRIPTION
</b><br>
<P>
This is a convenience function for extracting a captured substring into a given
buffer. The arguments are:
<pre>
  <i>subject</i>       Subject that has been successfully matched
  <i>ovector</i>       Offset vector that <b>pcre_exec()</b> used
  <i>stringcount</i>   Value returned by <b>pcre_exec()</b>
  <i>stringnumber</i>  Number of the required substring
  <i>buffer</i>        Buffer to receive the string
  <i>buffersize</i>    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.
