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.

Parameters

`closure`	`GClosure`
	The `GClosure` to which the marshaller belongs.
	The data is owned by the caller of the function.
`return_value`	`GValue`
	A `GValue` to store the return value. May be `NULL` if the callback of `closure` doesn’t return a value.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`instance`	`GTypeInstance`
	The instance on which the closure is invoked.
	The data is owned by the caller of the function.
`args`	`va_list`
	Va_list of arguments to be passed to the closure.
`marshal_data`	`gpointer`
	Additional data specified when registering the marshaller, see `g_closure_set_marshal()` and `g_closure_set_meta_marshal()`
	The argument can be `NULL`.
`n_params`	`int`
	The length of the `param_types` array.
`param_types`	An array of `GType`
	The `GType` of each argument from `args`.
	The length of the array is specified in the `n_params` argument.
	The data is owned by the caller of the function.
