  const GValue* param_values,
  gpointer invocation_hint,
  gpointer marshal_data


A GClosureMarshal function for use with signals with handlers that take two boxed pointers as arguments and return a boolean. If you have such a signal, you will probably also need to use an accumulator, such as g_signal_accumulator_true_handled().


closure GClosure

A GClosure.

 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 data is owned by the caller of the function.
n_param_values guint

The length of the param_values array.

param_values GValue

An array of GValues holding the arguments on which to invoke the callback of closure.

 The data is owned by the caller of the function.
invocation_hint gpointer

The invocation hint given as the last argument to g_closure_invoke().

marshal_data gpointer
