Use this function to write 16 bits in native format to a SDL_RWops as big-endian data.
size_t SDL_WriteBE16(SDL_RWops * dst, Uint16 value);
|dst||the stream to which data will be written|
|value||the data to be written, in native format|
Returns 1 on successful write, 0 on error.
SDL byteswaps the data only if necessary, so the application always specifies native format, and the data written will be in big-endian format.
This function is available since SDL 2.0.0.
