gboolean g_regex_match_all_full ( const GRegex* regex, const gchar* string, gssize string_len, gint start_position, GRegexMatchFlags match_options, GMatchInfo** match_info, GError** error )
Using the standard algorithm for regular expression matching only
the longest match in the
string is retrieved, it is not possible
to obtain all the available matches. For instance matching
This function uses a different algorithm (called DFA, i.e. deterministic
finite automaton), so it can retrieve all the possible matches, all
starting at the same point in the string. For instance matching
The number of matched strings is retrieved using
g_match_info_get_match_count(). To obtain the matched strings and
their position you can use, respectively,
g_match_info_fetch_pos(). Note that the strings are returned in
reverse order of length; that is, the longest matching string is
Note that the DFA algorithm is slower than the standard one and it is not able to capture substrings, so backreferences do not work.
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”.
G_REGEX_RAW is specified in the options,
string must be valid UTF-8.
GMatchInfo structure, used to get information on the match, is
match_info if not
NULL. Note that if
NULL then it is created even if the function returns
i.e. you must free it regardless if regular expression actually matched.

GMatchInfo internally. If
you use any

freeing or modifying
string then the behaviour is undefined.
