# SDL_Swap32BE

Swap a 32-bit value from bigendian to native byte order.

## Header File

Defined in [<SDL3/SDL_endian.h>](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.

## Thread Safety

It is safe to call this macro from any thread.

## Version

This macro is available since SDL 3.1.3.
