Hi,
Is it possible to find out the type of a pointer member from within q4?

Are q4 documents publicly
available?

You can, with the "catalog" and "fields" commands. See the online help or the documentation for information on these commands.

The q4 documentation can be found on your system under /usr/contrib/bin/Q4Docs.tar.Z.

Steve

Hi

Basic investigation of crash :-

crash commands
cd /var/adm/crash/core.*
q4 .
trace event 0

Stack trace from the first crash event:
stack trace for event 0

crash event was an HPMC <- typically hardware
or

crash event was a TOC <- hang or Serviceguard TOC
or

crash event was a Panic <- typically software

q4> examine panicstr using a
( fault here)

q4> load ???r crash_event_t from & crash_event_table until crash_event_ptr max 100
(loading 3 crash_event_t???s as an array (stopped bu ???until??? clause)

q4>runningprocs
(02 2 0x2)

q4> trace event 1
