I have searched the HP docs site (docs.hp.com)
for information about writing trap handlers for
HP-UX -- and found nothing. I also searched the
training and education site looking for device
driver writing classes and did not find anything.

IIRC other HP operating systems (RTE and MPE)
provided facilities for writing and installing
trap handlers to support real-time applications.

Are such facilities supported under HP-UX? HP
always had a significant business in real time
computing, and one would expect it carried over
into HP-UX.

What am I missing?

Thx,

try www.hp.com/go/dspp for the "Developer and
Solution Partner Program". Search for "device
driver" and follow the link for developing
drivers on hp-ux.

Drivers can have interrupt routines, but as far
as I know there is no supported mechanism for a
trap handler to be specified by a driver or
an application.

p.s.: Another site worth knowing about is
itrc.hp.com. If I were king, all these sites
would hang together better. But I'm not king.

As far as I'm concerned, a driver is
just a vehicle for injecting code
into the kernel (however politically
incorrect this may sound).
