Overview

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.

Availability

This hint is available since SDL 3.2.0.

From libsdl3-doc 3.2.10+ds-1 in Debian 13 (Trixie). Parsed by carta from the page's man source.
