| 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. |
