Correct.

I don't know why I'm checking the exception set at all...  Possibly
because out-of-band data used to cause memory corruption in Win95, so I
got in the habit of always terminating the program when I received it to
prevent further corruption.  That was fixed in Win95, and in any case has
nothing to do with OS/400... I don't know.

Yeah, like I said before, I think it's probably doing it to verify the
connection is operating properly.  If I were you, I'd set SO_OOBINLINE
with setsockopt() (so that out of band data doesn't sit in a buffer
indefinitely wasting resources) and then ignore the exception set, just
check read set...

Good Luck
