   40 This is a convenience function for extracting a captured substring into a given
   41 buffer. The arguments are:
   42 <pre>
   43   <i>subject</i>       Subject that has been successfully matched
   44   <i>ovector</i>       Offset vector that <b>pcre[16|32]_exec()</b> used
   45   <i>stringcount</i>   Value returned by <b>pcre[16|32]_exec()</b>
   46   <i>stringnumber</i>  Number of the required substring
   47   <i>buffer</i>        Buffer to receive the string
   48   <i>buffersize</i>    Size of buffer
   49 </pre>
   50 The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buffer was
   51 too small, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
