        should be treated as realtime.

HEADER FILE

       Defined in SDL3/SDL_hints.h

SYNOPSIS

       #include "SDL3/SDL.h"

       #define SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL SDL_THREAD_FORCE_REALTIME_TIME_CRITICAL"

DESCRIPTION

       On  some  platforms,  like  Linux, a realtime priority thread may be subject to restrictions that require
       special handling by the application. This hint exists to let SDL know that the app is prepared to  handle
       said restrictions.

       On Linux, SDL will apply the following configuration to any thread that becomes realtime:

       • The SCHED_RESET_ON_FORK bit will be set on the scheduling policy,

       • An RLIMIT_RTTIME budget will be configured to the rtkit specified limit.

       • Exceeding this limit will result in the kernel sending SIGKILL to the
         app, refer to the man pages for more information.

       The variable can be set to the following values:

       • "0": default platform specific behaviour

       • "1": Force

       SDL_THREAD_PRIORITY_TIME_CRITICAL
        to
         a realtime scheduling policy

       This hint should be set before calling

       SDL_SetCurrentThreadPriority ()

AVAILABILITY

       This hint is available since SDL 3.2.0.
