Flags which modify individual options.
G_OPTION_FLAG_HIDDEN
The option doesn't appear in --help
output.
G_OPTION_FLAG_IN_MAIN
The option appears in the main section of the
--help output, even if it is defined in a group.
G_OPTION_FLAG_REVERSE
For options of the G_OPTION_ARG_NONE kind, this flag
indicates that the sense of the option is reversed.
G_OPTION_FLAG_NO_ARG
For options of the G_OPTION_ARG_CALLBACK kind,
this flag indicates that the callback does not take any argument
(like a G_OPTION_ARG_NONE option). Since 2.8
G_OPTION_FLAG_FILENAME
For options of the G_OPTION_ARG_CALLBACK
kind, this flag indicates that the argument should be passed to the
callback in the GLib filename encoding rather than UTF-8. Since 2.8
G_OPTION_FLAG_OPTIONAL_ARG
For options of the G_OPTION_ARG_CALLBACK
kind, this flag indicates that the argument supply is optional. If no argument
is given then data of GOptionParseFunc will be set to NULL. Since 2.8
G_OPTION_FLAG_NOALIAS
This flag turns off the automatic conflict resolution
which prefixes long option names with groupname- if
there is a conflict. This option should only be used in situations where
aliasing is necessary to model some legacy commandline interface. It is
not safe to use this option, unless all option groups are under your
direct control. Since 2.8.
