Adds the options specified in entries to group.
a %NULL-terminated array of #GOptionEntrys
Frees a #GOptionGroup. Note that you must not free groups which have been added to a #GOptionContext.
Increments the reference count of group by one.
Sets the function which is used to translate user-visible strings,
for --help output. Different groups can use different
#GTranslateFuncs. If func is %NULL, strings are not translated.
If you are using gettext(), you only need to set the translation domain, see g_option_group_set_translation_domain().

A convenience function to use gettext() for translating user-visible strings.

A
GOptionGroupstruct defines the options in a single group. The struct has only private fields and should not be directly accessed.All options in a group share the same translation function. Libraries which need to parse commandline options are expected to provide a function for getting a
GOptionGroupholding their options, which the application can then add to its #GOptionContext.
