Regex.match

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.

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.

To retrieve all the non-overlapping matches of the pattern in string you can use g_match_info_next().

|[<!-- language="C" --> static void print_uppercase_words (const gchar *string) { // Print all uppercase-only words. GRegex *regex; GMatchInfo *match_info;

regex = g_regex_new ("[A-Z]+", 0, 0, NULL); g_regex_match (regex, string, 0, &match_info); while (g_match_info_matches (match_info)) { gchar *word = g_match_info_fetch (match_info, 0); g_print ("Found: %s\n", word); g_free (word); g_match_info_next (match_info, NULL); } g_match_info_free (match_info); g_regex_unref (regex); } ]|

@string is not copied and is used in #GMatchInfo internally. If you use any #GMatchInfo method (except g_match_info_free()) after freeing or modifying @string then the behaviour is undefined.
