I will read the GDB documentation in more depth, and will try a few
stint......
In the meantime, Quinn, if you could expand the showtask macro to
also include the status field (p->stat) of the BSD proc structure,
it would be great....
We won't be taking such a change back into kgmacros for the simple
reason that not all Mach tasks have associated BSD processes.
You could try using the following on proc structure address; not sure
how applicable it is, or if things have changed too much, though... it
has output vaguely like:
(gdb) showprocinfo 0x5006980
Process 0x05006980
name expect
pid:00004701 task:0x04f2f1d8 p_stat:2 parent pid:00000001
Cred: euid 501 ruid 501 svuid 501
Flags: 0x00004002
0x00000002 - has a controlling tty
!0x00000004 - process is 32 bit
0x00004000 - process has called exec
State: Run
