match_full

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 NOTBOL in the case of a pattern that begins with any kind of lookbehind assertion, such as "\b".

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 .

static void
print_uppercase_words (const gchar *string)
{
  // Print all uppercase-only words.
  GRegex *regex;
  GMatchInfo *match_info;
  GError *error = NULL;
  
  regex = g_regex_new ("[A-Z]+", 0, 0, 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_free (word);
      g_match_info_next (match_info, &error);
    }
  g_match_info_free (match_info);
  g_regex_unref (regex);
  if (error != NULL)
    {
      g_printerr ("Error while matching: %s\n", error->message);
      g_error_free (error);
    }
}

Parameters:

this	a Regex structure from Regex
string_len	the length of string, or -1 if string is nul-terminated
start_position	starting index of the string to match
match_options	match options
match_info	pointer to location where to store the MatchInfo, or null if you do not need it
string	the string to scan for matches

Returns:

true is the string matched, false otherwise
