NAME
SDL_HINT_EMSCRIPTEN_ASYNCIFY - Disable giving back control to the browser automatically when running with
asyncify.
SYNOPSIS
#include <SDL3/SDL_hints.h>
#define SDL_HINT_EMSCRIPTEN_ASYNCIFY "SDL_EMSCRIPTEN_ASYNCIFY"
DESCRIPTION
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.
