Declaration [src]

g_type_add_interface_check (
  gpointer check_data,
  GTypeInterfaceCheckFunc check_func

Description [src]

Adds a function to be called after an interface vtable is initialized for any class (i.e. after the interface_init member of GInterfaceInfo has been called).

This function is useful when you want to check an invariant that depends on the interfaces of a class. For instance, the implementation of GObject uses this facility to check that an object implements all of the properties that are defined on its interfaces.

Available since:2.4


check_data gpointer

check_func GTypeInterfaceCheckFunc

Function to be called after each interface is initialized.
