Regex.matchFull

Scans for a match in string for the pattern in regex. The match_options are combined with the match options specified when the regex structure was created, letting you have more flexibility in reusing #GRegex structures.

Setting start_position differs from just passing over a shortened string and setting G_REGEX_MATCH_NOTBOL in the case of a pattern that begins with any kind of lookbehind assertion, such as "\b".

Unless G_REGEX_RAW is specified in the options, string must be valid UTF-8.

A #GMatchInfo structure, used to get information on the match, is stored in match_info if not null. Note that if match_info is not null then it is created even if the function returns false, i.e. you must free it regardless if regular expression actually matched.

string is not copied and is used in #GMatchInfo internally. If you use any #GMatchInfo method (except [glib.match_info.MatchInfo.free]) after freeing or modifying string then the behaviour is undefined.

To retrieve all the non-overlapping matches of the pattern in string you can use [glib.match_info.MatchInfo.next].
