Greetings all,
I am writing some code that needs to run on several different
platforms and that plays with signals and the process's signal mask,
(flames and pity to /dev/null 8^) ) and I would like to be polite and
restore the signal mask to its previous state when I am done.
Unfortunately, I can find no way to get at the signal mask under Irix.
There are broad hints in /usr/include/sys/signal.h that it exists, but
it appears to be buried inaccessably deep in the kernal.
Ideally what I would like to find are the POSIX standard signal
handling routines, since that is what my "portable" code uses. In
particular, I would like to find sigprocmask(), sigaction(),
sigsuspend() and the sigset_t operators. I would be almost as happy
to find any set of routines that would let me implement these POSIX
routines. I would even be willing to do some mucking around in the
kernal, if I knew how and where to muck.
If anyone has any gems of wisdom on this topic, I would love to
hear from you. I do not follow comp.sys.sgi regularly, and am not on
the info-iris mailing list (though one of my coworkers is), so please
(also) send any responses to me directly by e-mail. Thanks in
advance! I am
