Re: Question on socket non block read

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Brad,

It sounds to me like you & I have had the opposite experiences.   I've 
never seen recv/send hang on a non-blocking socket.  (Blocking, yes... 
that's a different story.)

But I've definitely had problems with select() waiting for data when 
there's already data available.  As I mentioned before, this is a 
documented/expected situation with SSL sockets.  Though, I've seen it on 
non-SSL sockets, too, though I suspect that was a bug that was fixed 
years back.
