(This is the legacy documentation for stable SDL2, the current stable version; SDL3 is the current development version.)

SDL_HINT_EMSCRIPTEN_ASYNCIFY

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

Header File

Defined in SDL_hints.h

Syntax

#define SDL_HINT_EMSCRIPTEN_ASYNCIFY   "SDL_EMSCRIPTEN_ASYNCIFY"

Remarks

With -s ASYNCIFY, SDL2 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 (the default)
