If the read operation is implemented synchronously (this is the classic case), it will block and eventually time-out. The calling program should deal with the returned error.

If the read operation is asynchronous (as it will be in modern programming languages), the underlying library might provide an error callback, or you'll have to schedule a timeout task yourself.
