FIONBIO/FIOASYNC

[PAAAAAR%CALSTATE.BITNET at wiscvm.wisc.EDU]

Can anyone tell me what FIONBIO and FIOASYNC mean? I found them in the
login.c code that I hacked to get our current login process. I couldn't
find a definition for them and so removed the ioctl()s that refered to it - th
result has worked for 6 months - but I need to be sure that they don't do
anything useful to sleep well at nights.
 
The code was in the network contributions. We run a PDP 11/24 with DZ11s.
