source_set_dummy_callback

Sets a dummy callback for source.

The callback will do nothing, and if the source expects a bool return value, it will return true. (If the source expects any other type of return value, it will return a 0/ null value; whatever Value initializes a Value to for that type.)

If the source is not one of the standard GLib types, the closure_callback and closure_marshal fields of the SourceFuncs structure must have been filled in with pointers to appropriate functions.

Parameters:
