A string specifying additional information to use with SDL_SetThreadPriority.
Defined in SDL_hints.h
#define SDL_HINT_THREAD_PRIORITY_POLICY "SDL_THREAD_PRIORITY_POLICY"
By default SDL_SetThreadPriority 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.
