Re^6: No data received on client socket

undef *is* always false. Again, I'm not talking about undef. That $!'s value is undefined (as opposed to $! being undefined) means $! could be 0, it could be -123, it could be the string "the answer to life, the universe, everything".

:) If you read my post more carefully that is exactly what I was talking about. :) Actually, just peeked at pp_sys.c of perl-5.8.8 and verified that `$!` is set to 0 unconditionally there with call to `SETERRNO(0,0)` before reading file handle. Thus you can safely rely on `$!`'s value even if no system error occures. BR	[reply] [d/l] [select]
