NAME

       SDL_HINT_MAC_OPENGL_ASYNC_DISPATCH  -  A  variable controlling whether dispatching OpenGL context updates
       should block the dispatching thread until the main thread finishes processing on macOS.

HEADER FILE

       Defined in SDL3/SDL_hints.h

SYNOPSIS

       #include "SDL3/SDL.h"

       #define SDL_HINT_MAC_OPENGL_ASYNC_DISPATCH SDL_MAC_OPENGL_ASYNC_DISPATCH"

DESCRIPTION

       The variable can be set to the following values:

       • "0": Dispatching OpenGL context updates will block the dispatching thread
         until the main thread finishes processing. (default)

       • "1": Dispatching OpenGL context updates will allow the dispatching thread
         to continue execution.

       Generally you want the default, but if you have OpenGL code in a background thread on a Mac, and the main
       thread hangs because it's waiting for that background thread, but that background thread is also  hanging
       because it's waiting for the main thread to do an update, this might fix your issue.

       This hint can be set anytime.

AVAILABILITY

       This hint is available since SDL 3.2.0.
