SDL_WriteIO - Write to an SDL_IOStream data stream.

       This function is available since SDL 3.2.0.

       This  function writes exactly size bytes from the area pointed at by ptr to the stream. If this fails for
       any reason, it'll return less than size to demonstrate how far  the  write  progressed.  On  success,  it
       returns size.

       On  error, this function still attempts to write as much as possible, so it might return a positive value
       less than the requested write size.

       The caller can use SDL_GetIOStatus() to determine if the problem is recoverable, such as  a  non-blocking
       write that can simply be retried later, or a fatal error.
