Hi Bruno
OK, the highest number for any SIG<something> is 31, so NSIG should really be
32.
The only SA_<something> Macros I can find are SA_DATA_SITE in <sys/socket.h>,
most probably unrated, and SA_NOCLDSTOP and SA_RESERVED_31 in <signal.h>, and
nothing that looks remotely like a replacement, signal.h attached
Bye, Jojo

Subject: Re: <signal.h> on HP-NonStop
Hello Joachim,
Please, let's use different mails with different subject for each topic.
Otherwise I cannot keep track which issues have been dealt with, and the
conversation dies down in confusion.

NSIG should be larger than any predefined signal value. Since you say that your
system has 33 signals, the value 32 is not right. Probably 33, 34, or 64 is
better then. You need to look at the values in your <signal.h>.
And the definition belongs in <signal.h>.

These two are specified by POSIX
<http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/signal.h.html>.
Does NonStop Kernel really lack these flags, or are they merely available under
different names?
