OptionGroup

Description:

public OptionGroup (string name, string description, string help_description, void* user_data = null, DestroyNotify? destroy = null)

Creates a new OptionGroup.

description is typically used to provide a title for the group. If so, it is recommended that it’s written in title case, and has a trailing colon so that it matches the style of built-in GLib group titles such as ‘Application Options:’.

Parameters:

name	the name for the option group, this is used to provide help for the options in this group with `--help-``name`
description	a description for this group to be shown in `--help`. This string is translated using the translation domain or translation function of the group
help_description	a description for the `--help-``name` option. This string is translated using the translation domain or translation function of the group
user_data	user data that will be passed to the pre- and post-parse hooks, the error hook and to callbacks of g_option_arg_callback options, or null
destroy	a function that will be called to free `user_data`, or null

Returns:

a newly created option group. It should be added to a OptionContext or freed with g_option_group_unref.
