Scans for a match in
string for the pattern in this.
match_options are combined with the match options specified when the this structure was
created, letting you have more flexibility in reusing Regex structures.
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.
print_uppercase_words (const gchar *string)
// Print all uppercase-only words.
GError *error = NULL;
regex = g_regex_new ("[A-Z]+", G_REGEX_DEFAULT, G_REGEX_MATCH_DEFAULT, NULL);
g_regex_match_full (regex, string, -1, 0, 0, &match_info, &error);
while (g_match_info_matches (match_info))
gchar *word = g_match_info_fetch (match_info, 0);
g_print ("Found: %s\n", word);
g_match_info_next (match_info, &error);
if (error != NULL)
g_printerr ("Error while matching: %s\n", error->message);
the length of

true is the string matched, false otherwise
