Типы

SDL_TimerCallback

typedef Uint32(SDLCALL * SDL_TimerCallback) (Uint32 interval, void *param)

Function prototype for the timer callback function.

The callback function is passed the current timer interval and returns the next timer interval. If the returned value is the same as the one passed in, the periodic alarm continues, otherwise a new alarm is scheduled. If the callback returns 0, the periodic alarm is cancelled.

Граф вызова функции:

SDL_AddTimer()

DECLSPEC SDL_TimerID SDLCALL SDL_AddTimer	(	Uint32	interval,
		SDL_TimerCallback	callback,
		void *	param
	)

Add a new timer to the pool of timers already running.

Возвращает

A timer ID, or 0 when an error occurs.

SDL_RemoveTimer()

DECLSPEC SDL_bool SDLCALL SDL_RemoveTimer

(

SDL_TimerID

id

)
