 180  * @G_REGEX_CASELESS: Letters in the pattern match both upper- and
 181  *     lowercase letters. This option can be changed within a pattern
 182  *     by a "(?i)" option setting.
 183  * @G_REGEX_MULTILINE: By default, GRegex treats the strings as consisting
 184  *     of a single line of characters (even if it actually contains
 185  *     newlines). The "start of line" metacharacter ("^") matches only
 186  *     at the start of the string, while the "end of line" metacharacter
 187  *     ("$") matches only at the end of the string, or before a terminating
 188  *     newline (unless #G_REGEX_DOLLAR_ENDONLY is set). When
 189  *     #G_REGEX_MULTILINE is set, the "start of line" and "end of line"
 190  *     constructs match immediately following or immediately before any
 191  *     newline in the string, respectively, as well as at the very start
 192  *     and end. This can be changed within a pattern by a "(?m)" option
 193  *     setting.
 194  * @G_REGEX_DOTALL: A dot metacharater (".") in the pattern matches all
 195  *     characters, including newlines. Without it, newlines are excluded.
 196  *     This option can be changed within a pattern by a ("?s") option setting.
 197  * @G_REGEX_EXTENDED: Whitespace data characters in the pattern are
 198  *     totally ignored except when escaped or inside a character class.
 199  *     Whitespace does not include the VT character (code 11). In addition,
 200  *     characters between an unescaped "#" outside a character class and
 201  *     the next newline character, inclusive, are also ignored. This can
 202  *     be changed within a pattern by a "(?x)" option setting.
 203  * @G_REGEX_ANCHORED: The pattern is forced to be "anchored", that is,
 204  *     it is constrained to match only at the first matching point in the
 205  *     string that is being searched. This effect can also be achieved by
 206  *     appropriate constructs in the pattern itself such as the "^"
 207  *     metacharater.
 208  * @G_REGEX_DOLLAR_ENDONLY: A dollar metacharacter ("$") in the pattern
 209  *     matches only at the end of the string. Without this option, a
 210  *     dollar also matches immediately before the final character if
 211  *     it is a newline (but not before any other newlines). This option
 212  *     is ignored if #G_REGEX_MULTILINE is set.
 213  * @G_REGEX_UNGREEDY: Inverts the "greediness" of the quantifiers so that
 214  *     they are not greedy by default, but become greedy if followed by "?".
 215  *     It can also be set by a "(?U)" option setting within the pattern.
 216  * @G_REGEX_RAW: Usually strings must be valid UTF-8 strings, using this
 217  *     flag they are considered as a raw sequence of bytes.
 218  *     @G_REGEX_NO_AUTO_CAPTURE: Disables the use of numbered capturing
 219  *     parentheses in the pattern. Any opening parenthesis that is not
 220  *     followed by "?" behaves as if it were followed by "?:" but named
 221  *     parentheses can still be used for capturing (and they acquire numbers
 222  *     in the usual way).
 223  * @G_REGEX_OPTIMIZE: Optimize the regular expression. If the pattern will
 224  *     be used many times, then it may be worth the effort to optimize it
 225  *     to improve the speed of matches.
 226  * @G_REGEX_DUPNAMES: Names used to identify capturing subpatterns need not
 227  *     be unique. This can be helpful for certain types of pattern when it
 228  *     is known that only one instance of the named subpattern can ever be
 229  *     matched.
 230  * @G_REGEX_NEWLINE_CR: Usually any newline character is recognized, if this
 231  *     option is set, the only recognized newline character is '\r'.
 232  * @G_REGEX_NEWLINE_LF: Usually any newline character is recognized, if this
 233  *     option is set, the only recognized newline character is '\n'.
 234  * @G_REGEX_NEWLINE_CRLF: Usually any newline character is recognized, if this
 235  *     option is set, the only recognized newline character sequence is '\r\n'.

 274  * @G_REGEX_MATCH_NOTEOL: Specifies that the end of the subject string is
 275  *     not the end of a line, so the dollar metacharacter should not match

 283  *     entire match fails. For example, if the pattern "a?b?" is applied to

 285  *     at the start of the string. With this flag set, this match is not
