+DESCRIPTION
+</b><br>
+<P>
+This is a convenience function for extracting a captured substring into a given
+buffer. The arguments are:
+<pre>
+ <i>match_data</i> The match data block for the match
+ <i>number</i> Number of the required substring
+ <i>buffer</i> Buffer to receive the string
+ <i>bufflen</i> Length of buffer
+</pre>
+The <i>bufflen</i> variable is updated with the length of the extracted string,
+excluding the terminating zero. The yield of the function is zero for success
+or one of the following error numbers:
+<pre>
+ PCRE2_ERROR_NOSUBSTRING there are no groups of that number
+ PCRE2_ERROR_UNAVAILBLE the ovector was too small for that group
+ PCRE2_ERROR_UNSET the group did not participate in the match
+ PCRE2_ERROR_NOMEMORY the buffer is too small
+
+</PRE>
