(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_SwapBE64

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

Header File

Defined in SDL_endian.h, but apps should use #include <SDL3/SDL.h>

Syntax

#define SDL_SwapBE64(x) SwapOnlyIfNecessary(x)

Macro Parameters

x	the value to swap, in bigendian byte order.

Return Value

Returns x in native byte order.

Remarks

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

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

Version

This macro is available since SDL 3.0.0.
