Function

GObjectVaClosureMarshal

Declaration

void
(* GVaClosureMarshal) (
  GClosure* closure,
  GValue* return_value,
  GObjectTypeInstance* instance,
  va_list args,
  gpointer marshal_data,
  int n_params,
  GType* param_types
)

Description

This is the signature of va_list marshaller functions, an optional marshaller that can be used in some situations to avoid marshalling the signal argument into GValues.

This function is not directly available to language bindings
