NAME

       SDL_CPUPauseInstruction - A macro to insert a CPU-specific "pause" instruction into the program.

HEADER FILE

       Defined in SDL3/SDL_atomic.h

SYNOPSIS

       #include "SDL3/SDL.h"

       #define SDL_CPUPauseInstruction() DoACPUPauseInACompilerAndArchitectureSpecificWay

DESCRIPTION

       This can be useful in busy-wait loops, as it serves as a hint to the CPU as to the program's intent; some
       CPUs  can use this to do more efficient processing. On some platforms, this doesn't do anything, so using
       this macro might just be a harmless no-op.

       Note that if you are busy-waiting, there are often more-efficient approaches with  other  synchronization
       primitives: mutexes, semaphores, condition variables, etc.

THREAD SAFETY

       This macro is safe to use from any thread.

AVAILABILITY

       This macro is available since SDL 3.2.0.
