       SDL_CompilerBarrier - Mark a compiler barrier.

HEADER FILE

       Defined in SDL3/SDL_atomic.h

SYNOPSIS

       #include "SDL3/SDL.h"

       #define SDL_CompilerBarrier() DoCompilerSpecificReadWriteBarrier()

DESCRIPTION

       A  compiler  barrier prevents the compiler from reordering reads and writes to globally visible variables
       across the call.

       This macro only prevents the compiler from reordering reads and writes, it does not prevent the CPU  from
       reordering  reads  and  writes.  However, all of the atomic operations that modify memory are full memory
       barriers.

THREAD SAFETY

       Obviously this macro is safe to use from any thread at any time, but if you find yourself  needing  this,
       you are probably dealing with some very sensitive code; be careful!

AVAILABILITY

       This macro is available since SDL 3.2.0.
