sync printing with refresh rate

I'd like to make a game in C that runs in a terminal/fb console. How can I get the screen to update only once for each time the screen refreshes?

Thanks, but I'm looking for specific code that I could adapt to make the screen print at a desired framerate. Doesn't need to be the full refresh rate, but I need to be able to print to the screen in a way that won't cause flickering.
