Function Documentation

glRegisterEvents()

void glRegisterEvents	(	glEventHandler	callback,
		void *	user = NULL,
		uint32_t	display = 0
	)

Register an event message handler that will be called with events.

Parameters

callback	function pointer to the event message handler callback
user	optional user-specified pointer that will be passed to all invocations of this event handler (typically an object)
display	optional display ID of the glDisplay instance to use

glUnregisterEvents()

void glUnregisterEvents	(	glEventHandler	callback,
		void *	user = NULL
	)

UnregisterEventHandler() will search for previously registered event handlers that have the same function pointer and/or user pointer, and remove them for being called again in the future.
