DESCRIPTION

|
|
This is a convenience function for extracting a captured substring, identified
|
||
|
|
by name, into a given buffer. The arguments are:
|
||
|
|
<pre>
|
||
|
|
<i>match_data</i> The match data block for the match
|
||
|
|
<i>name</i> Name of the required substring
|
||
|
|
<i>buffer</i> Buffer to receive the string
|
||
|
|
<i>bufflen</i> Length of buffer (code units)
|
||
|
|
</pre>
|
||
|
|
The <i>bufflen</i> variable is updated to contain the length of the extracted
|
||
|
|
string, excluding the trailing zero. The yield of the function is zero for
|
||
|
|
success, PCRE2_ERROR_NOMEMORY if the buffer is too small, or
|
||
|
|
PCRE2_ERROR_NOSUBSTRING if the string name is invalid.
