30 This is a convenience function for extracting a captured substring into a given
31 buffer. The arguments are:
32 <pre>
33 <i>subject</i> Subject that has been successfully matched
34 <i>ovector</i> Offset vector that <b>pcre_exec()</b> used
35 <i>stringcount</i> Value returned by <b>pcre_exec()</b>
36 <i>stringnumber</i> Number of the required substring
37 <i>buffer</i> Buffer to receive the string
38 <i>buffersize</i> Size of buffer
39 </pre>
40 The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buffer was
41 too small, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
