Close and free an allocated SDL_IOStream structure.
SDL_CloseIO() closes and cleans up the SDL_IOStream stream. It releases any
resources used by the stream and frees the SDL_IOStream itself. This
returns true on success, or false if the stream failed to flush to its
output (e.g. to disk).
Note that if this fails to flush the stream for any reason, this function
reports an error, but the SDL_IOStream is still invalid once this function
returns.
This call flushes any buffered writes to the operating system, but there
are no guarantees that those writes have gone to physical media; they might
be in the OS's file cache, waiting to go to disk later. If it's absolutely
crucial that writes go to disk immediately, so they are definitely stored
even if the power fails before the file cache would have caught up, one
should call SDL_FlushIO() before closing. Note that flushing takes time and
makes the system and your app operate less efficiently, so do so sparingly.
