###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_Swap32BE Swap a 32-bit value from bigendian to native byte order. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_endian.h) ## Syntax ```c #define SDL_Swap32BE(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. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryEndian](CategoryEndian)
