Function

GObjectclear_signal_handler

since: 2.62

Declaration [src]

void
g_clear_signal_handler (
  gulong* handler_id_ptr,
  GObject* instance
)

Description [src]

Disconnects a handler from instance so it will not be called during any future or currently ongoing emissions of the signal it has been connected to. The handler_id_ptr is then set to zero, which is never a valid handler ID value (see g_signal_connect()).

If the handler ID is 0 then this function does nothing.

There is also a macro version of this function so that the code will be inlined.

Available since: 2.62

Parameters

Type: gulong*

A pointer to a handler ID (of type #gulong) of the handler to be disconnected.

The data is owned by the caller of the function.

instance

Type: GObject

The instance to remove the signal handler from. This pointer may be NULL or invalid, if the handler ID is zero.

The data is owned by the caller of the function.
