| DESCRIPTION
 | |
| </b><br>
 | |
| <P>
 | |
| 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 or one of the following error numbers:
 | |
| <pre>
 | |
|   PCRE2_ERROR_NOSUBSTRING   there are no groups of that name
 | |
|   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 not big enough
 | |
| </pre>
 | |
| If there is more than one group with the given name, the first one that is set
 | |
| is returned. In this situation PCRE2_ERROR_UNSET means that no group with the
 | |
| given name was set.
 | |
