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[16|32]_exec()</b> used
|
|
|
|
|
<i>stringcount</i> Value returned by <b>pcre[16|32]_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.
