add_interface

Description:

public void add_interface (Type instance_type, Type interface_type, InterfaceInfo interface_info)

Registers an additional interface for a type, whose interface lives in the given type plugin.

If the interface was already registered for the type in this plugin, nothing will be done.

As long as any instances of the type exist, the type plugin will not be unloaded.

Since 2.56 if this is null this will call g_type_add_interface_static instead. This can be used when making a static build of the module.

this	a TypeModule
instance_type	type to which to add the interface.
interface_type	interface type to add
interface_info	type information structure
