NAME
SDL_HINT_THREAD_PRIORITY_POLICY - A string specifying additional information to use with
SDL_SetCurrentThreadPriority.
SYNOPSIS
#include <SDL3/SDL_hints.h>
#define SDL_HINT_THREAD_PRIORITY_POLICY "SDL_THREAD_PRIORITY_POLICY"
DESCRIPTION
By default SDL_SetCurrentThreadPriority will make appropriate system changes in order to apply a thread
priority. For example on systems using pthreads the scheduler policy is changed automatically to a policy
that works well with a given priority. Code which has specific requirements can override SDL's default
behavior with this hint.
pthread hint values are "current", "other", "fifo" and "rr". Currently no other platform hint values are
defined but may be in the future.
On Linux, the kernel may send SIGKILL to realtime tasks which exceed the distro configured execution
budget for rtkit. This budget can be queried through RLIMIT_RTTIME after calling
SDL_SetCurrentThreadPriority().
This hint should be set before calling SDL_SetCurrentThreadPriority()
AVAILABILITY
This hint is available since SDL 3.2.0.
