I've noticed that several socket options mentioned in the manpages are
missing from Linux, at least in my libc version (4.6.27):
SO_SNDLOWAT
SO_RCVLOWAT
SO_SNDTIMEO
SO_RCVTIMEO
etc...
They are mentioned in getsockopt(2).
I am currently involved in writing a large networking application for
a Fortune 5 company, and it needs to run under Linux 1.2 (primary importance)
and AIX 3.2 (as a backup system). Life would be great if Linux supported
these options. AIX does, by the way...
Any chance they'll come along? I'm working around the timeouts by using
SIGALRM, but I want a way to guarantee that a read on a tcp connection will
block until the full requested amount is received, or until the timeout
elapses. The manpage for recv() indicates that it might return with
a partial amount of the data requested.
Then again, maybe it's just time to update the manpages. :)
Thanks
Jeff
