The return-code for that might be a -1 (making a comparison for that case more apt - will have to test). Almost all of my build-logs (reviewing my build-logs, I see one out of ~60 combinations failing for Linux) for Linux show it working - probably depends upon the environment. > If i compile the C test myself, adding a printf at the end, ret==0 after the > poll(). > > The buildds are returning > > "checking if poll really works... no" > > yet Linux's poll() is fine. usually (I seem to recall that the original reason for testing poll vs select was in fact a buggy implementation on Linux - that's been a while). -- Thomas E.
