# SDL_WriteBE64

Use this function to write 64 bits in native format to a [SDL_RWops](SDL_RWops) as big-endian data.

## Header File

Defined in [SDL_rwops.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_rwops.h), but apps should _only_ `#include "SDL.h"`!

## Syntax

```c
size_t SDL_WriteBE64(SDL_RWops * dst, Uint64 value);

```

## Function Parameters

|               |                                          |
| ------------- | ---------------------------------------- |
| **dst**       | the stream to which data will be written |
| **value**     | the data to be written, in native format |

## Return Value

Returns 1 on successful write, 0 on error.

## Remarks

SDL byteswaps the data only if necessary, so the application always
specifies native format, and the data written will be in big-endian format.

## Version

This function is available since SDL 2.0.0.
