I was under the impression that SDL_Delay was meant for delaying a thread in a multi-threaded application. Not that it necessarily matters.

I personally use a timer approach (see this [ http://lazyfoo.net/SDL_tutorials/lesson14/index.php] tutorial).

My standard SDL main function looks a little like this C++ Pseudocode:

int main()
{
initialize_everything();
while (gamestate != QUIT)
{
timer.start();
switch (gamestate)
{
call the correct state object's event loop and draw function.
}
while (timer.getTicks() <= 1000 / FPS_CAP);
print_fps();
}
}

The documentation wiki for SDL_Delay() is very sparse, and doesn't go into what the method is meant to be used for. My guess is that using it anyplace you want the thread to background is fair game.

I'd seen the tutorial you mentioned while looking for ways to throttle framerate, and noted this in the conclusion:

I'll admit, using a while loop to wait is a bit wasteful. Because the program is repeatedly checking if the time is up you're going using up 100% CPU. Another way is to make the program sleep using SDL_Delay(). This will drastically cut the amount of CPU the program uses. I could show you the code that does it but I have to let you figure some things out for yourself =).

I prefer SDL_Delay() personally because it means my computer fans don't kick in every time I run the game. ;)

Looks like you can use HTML in the comments. (I'd forgotten, if you must know.)
