add_main_option
Description:
public void add_main_option (string long_name, char short_name, OptionFlags flags, OptionArg arg, string description, string? arg_description)
Add an option to be handled by this.
Calling this function is the equivalent of calling add_main_option_entries with a single OptionEntry that has its arg_data member set to null.
The parsed arguments will be packed into a VariantDict which is passed to handle_local_options. If g_application_handles_command_line is set, then it will also be sent to the primary instance. See add_main_option_entries for more details.
See OptionEntry for more documentation of the arguments.
