SDL_Swap64BE(3) SDL3 FUNCTIONS SDL_Swap64BE(3)

SDL_Swap64BE - Swap a 64-bit value from bigendian to native byte order.

Defined in SDL3/SDL_endian.h

#include "SDL3/SDL.h"
#define SDL_Swap64BE(x) SwapOnlyIfNecessary(x)

If this is running on a bigendian system, x is returned unchanged.

This macro never references x more than once, avoiding side effects.

Returns x in native byte order.

It is safe to call this macro from any thread.

This macro is available since SDL 3.2.0.
