The other interface appeared in R3 and is accessed via the "sigset" system
call (same arguments as "signal"). Signal handlers invoked after a sigset
behave just like Berkeley signals, that is ensuing signals of the same type
are blocked while the signal handler is running. Just put a
#define signal sigset
at the start of your program and see if that fixes the problems. Your
program will certainly be more reliable.
I have been looking at sigset(2) and signal(2) in the SYSV.3 docs. The above
should work. But nowhere in the documentation is the replacing of the
signal call with a sigset call explicitly stated as method of using the new
signals mechinasm. My problem is that on a OPUS 32532 system running V.3 I
get unresolved references for _sigset when I try the above method. A search
through the libraries doesn't find sigset, signal is in libc; but no sigset.
I already know OPUS didn't implement shared libraries in their V.3, did they
forget the new signals also? If not where did they hide sigset?

If not where did they hide sigset? Sigset was added to sysV.3.2 only since V.3.2; I think Opus's port is of an earlier version. -- Amos Shapir My other CPU is a NS32532 National Semiconductor, 2900 semiconductor Dr., Santa Clara, CA 95052-8090 amos@nsc.com or amos%taux01@nsc.com
