NAME

       SDL_MemoryBarrierAcquire - Insert a memory acquire barrier (macro version).

HEADER FILE

       Defined in SDL3/SDL_atomic.h

SYNOPSIS

       #include "SDL3/SDL.h"

       #define SDL_MemoryBarrierAcquire() SDL_MemoryBarrierAcquireFunction()

DESCRIPTION

       Please see SDL_MemoryBarrierRelease
        for the details on what memory barriers are and when to use them.

       This  is the macro version of this functionality; if possible, SDL will use compiler intrinsics or inline
       assembly, but some platforms might need to call the function version of this,

       SDL_MemoryBarrierAcquireFunction , to do the heavy lifting. Apps that can use the macro should  favor  it
       over the function.

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.
