the callback function
the #GClosure
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().
A #GClosure.
A #GValue to store the return value. May be %NULL if the callback of closure doesn't return a value.
The length of the param_values array.
An array of #GValues holding the arguments on which to invoke the callback of closure.
The invocation hint given as the last argument to g_closure_invoke().
Additional data specified when registering the marshaller, see g_closure_set_marshal() and g_closure_set_meta_marshal()
A marshaller for a #GCClosure with a callback of type
gboolean (*callback) (gpointer instance, gint arg1, gpointer user_data) where the #gint parameter
denotes a flags type.
the #GClosure to which the marshaller belongs
a #GValue which can store the returned #gboolean

additional data specified when registering the marshaller
A generic marshaller function implemented via libffi.
Normally this function is not passed explicitly to g_signal_new(), but used automatically by GLib when specifying a %NULL marshaller.
