Use this function to write 64 bits in native format to an SDL_RWops as little-endian data.
SDL_bool SDL_WriteS64LE(SDL_RWops *dst, Sint64 value);
|dst||the stream to which data will be written|
|value||the data to be written, in native format|
Returns SDL_TRUE on successful write, SDL_FALSE on failure; call SDL_GetError() for more information.
SDL byteswaps the data only if necessary, so the application always specifies native format, and the data written will be in little-endian format.
This function is available since SDL 3.0.0.
