SDL_HINT_EMSCRIPTEN_ASYNCIFY(3) SDL3 FUNCTIONS SDL_HINT_EMSCRIPTEN_ASYNCIFY(3)

SDL_HINT_EMSCRIPTEN_ASYNCIFY - Disable giving back control to the browser automatically when running with asyncify.

Defined in SDL3/SDL_hints.h

#include "SDL3/SDL.h"
#define SDL_HINT_EMSCRIPTEN_ASYNCIFY SDL_EMSCRIPTEN_ASYNCIFY"

With -s ASYNCIFY, SDL calls emscripten_sleep during operations such as refreshing the screen or polling events.

This hint only applies to the emscripten platform.

The variable can be set to the following values:

• "0": Disable emscripten_sleep calls (if you give back browser control
manually or use asyncify for other purposes).

• "1": Enable emscripten_sleep calls. (default)

This hint can be set anytime.

This hint is available since SDL 3.2.0.
