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