Select is not documented to work on null streams but it does not raise error 141 141 --- Not implemented for this stream class on this system. However it does say data is available [poll 18]: select([null], 0, K). K = [null] Yes (0.00s cpu) But of course no data is available [poll 19]: get(null,K). K = -1 Yes (0.00s cpu) [poll 20]: I believe it should work on the null stream and always return that no data is available.
