DESCRIPTION

|
</b><br>
|
|
<P>
|
|
This function returns the length of a matched substring, identified by number.
|
|
The arguments are:
|
|
<pre>
|
|
<i>match_data</i> The match data block for the match
|
|
<i>number</i> The substring number
|
|
<i>length</i> Where to return the length, or NULL
|
|
</pre>
|
|
The third argument may be NULL if all you want to know is whether or not a
|
|
substring is set. The yield is zero on success, or a negative error code
|
|
otherwise. After a partial match, only substring 0 is available.
