GI.GLib.Structs.OptionEntry
Description
A GOptionEntry struct defines a single option. To have an effect, they must be added to a #GOptionGroup with g_option_context_add_main_entries() or g_option_group_add_entries().
- newtype OptionEntry = OptionEntry (ForeignPtr OptionEntry)
- newZeroOptionEntry :: MonadIO m => m OptionEntry
