Declaration [src]
gboolean
g_regex_match (
const GRegex* regex,
const gchar* string,
GRegexMatchFlags match_options,
GMatchInfo** match_info
)
Description [src]
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.
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.
To retrieve all the non-overlapping matches of the pattern in string you can use g_match_info_next().
static void
print_uppercase_words (const gchar *string)
{
// Print all uppercase-only words.
GRegex *regex;
GMatchInfo *match_info;
regex = g_regex_new ("[A-Z]+", G_REGEX_DEFAULT, G_REGEX_MATCH_DEFAULT, 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.
