public bool match_full (string str, ssize_t string_len = -1, int start_position = 0, RegexMatchFlags match_options = 0, out MatchInfo match_info = null) throws RegexError

Scans for a match in string for the pattern in this.

The match_options are combined with the match options specified when the this structure was created, letting you have more flexibility in reusing Regex 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 MatchInfo 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 MatchInfo internally. If you use any MatchInfo method (except g_match_info_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 next.

a Regex structure from Regex


the length of string, in bytes, or -1 if string is nul-terminated


starting index of the string to match, in bytes


match options


pointer to location where to store the MatchInfo, or null if you do not need it


the string to scan for matches


true is the string matched, false otherwise
