A sentinel does provide a work around, but it also passes the problem onto the caller rather than the callee
The callee can easily take care of it -- just block until more is ready. If blocking is not an option, then the caller has to deal with it no matter how callee is implemented -- an exception, a sentinel, or some signal that says "nope, nothing for ya! try back later!"
