Type Alias GClosureMarshal

pub type GClosureMarshal = Option<unsafe extern "C" fn(closure: *mut GClosure, return_value: *mut GValue, n_param_values: guint, param_values: *const GValue, invocation_hint: gpointer, marshal_data: gpointer)>;

GClosureMarshal: @closure: the #GClosure to which the marshaller belongs @return_value: (nullable): a #GValue to store the return value. May be %NULL if the callback of @closure doesn’t return a value. @n_param_values: the length of the @param_values array @param_values: (array length=n_param_values): an array of #GValues holding the arguments on which to invoke the callback of @closure @invocation_hint: (nullable): the invocation hint given as the last argument to g_closure_invoke() @marshal_data: (nullable): additional data specified when registering the marshaller, see g_closure_set_marshal() and g_closure_set_meta_marshal()

The type used for marshaller functions.
