Sigstack and BSD 4.2

[ron at celerity.UUCP]

[]

Being one of your average searchers-after-truth, I've  been  ear-
nestly  perusing the pages of my BSD 4.2 documentation, register-
ing some amazement over "how things have changed",  and  in  most
cases  admiring  some of the new bells and whistles and trying to
imagine what I will do with them all. This brings me to the  sub-
ject  of  this  tome and the reason for troubling you all with my
chatter.

Allowing for the elegance of the new signaling mechanism, what on
earth  can  you do with the alternate signal stack? I have looked
at the documentation, examined  the  listings  and  while  I  can
understand how they are implemented, I, as yet, haven't been able
to understand why I need them.

In spite of the well earned reputation for restraint and bashful-
ness that the participants in this news group have, I have decid-
ed to throw caution to the wind, admit my ignorance  and  be  as-
sailed for my cloddish ignorance.

Seriously, I'll probably be surprised at the  simplicity  of  the
answer,  but  I  am floundering on this one. The documentation to
which I have alluded is sections 2 and 3 of the BSD 4.2 UNIX Pro-
grammers  manual. If there are other documents I have overlooked,
or if  anyone  simply  has  the  answer,  I  would  appreciate  a
response.

Of course, many thanks in advance,
