Timer callback pushing an event!?

SDL Development

Hrm… I’d like my program to sit pretty much idle until the
timer goes off. So in my main loop, I’ll be doing an
"SDL_WaitEvent()".

When the timer goes off, I need to let the main loop know to wake up
and smell the SDL_USEREVENT I’m sending it…

However, from the docs:

“The timer callback function may run in a different thread than your main
program, and so shouldn’t call any functions from within itself.”

This means that I really shouldn’t be using “SDL_PushEvent()” in my
callback function.

So… how do I do this? Should I just switch to “SDL_PollEvent()” and
have the main loop run /mostly/ idle (by using a large SDL_Delay())???

Since SDL_PushEvent() is thread-safe, you can call it from within your
timer function. :slight_smile:
