<P>
<b>int pcre2_substring_copy_bynumber(pcre2_match_data *<i>match_data</i>,</b>
<b> unsigned int <i>number</i>, PCRE2_UCHAR *<i>buffer</i>,</b>
<b> PCRE2_SIZE *<i>bufflen</i>);</b>

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,
PCRE2_ERROR_NOMEMORY if the buffer was too small, or PCRE2_ERROR_NOSUBSTRING if
the string number is invalid.
