(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_HINT_MAIN_CALLBACK_RATE

Request SDL_AppIterate() be called at a specific rate.

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

#define SDL_HINT_MAIN_CALLBACK_RATE "SDL_MAIN_CALLBACK_RATE"

Remarks

This number is in Hz, so "60" means try to iterate 60 times per second.

On some platforms, or if you are using SDL_main instead of SDL_AppIterate, this hint is ignored. When the hint can be used, it is allowed to be changed at any time.

This defaults to 60, and specifying NULL for the hint's value will restore the default.

This hint can be set anytime.

Version

This hint is available since SDL 3.1.3.
