Have you checked to see if you can make use of the information provided
by procfs(5)? In particular, I note:
...
status The process status. This file is read-only and returns a single
line containing multiple space-separated fields as follows:
o command name
o process id
...
o the process start time in seconds and microseconds, comma
separated.
o the user time in seconds and microseconds, comma separated.
o the system time in seconds and microseconds, comma separated.
o the wait channel message
....
Thus, on my laptop, I see:
g1-35(6.4-S)[1] cat /proc/`pgrep firefox-bin`/status
firefox-bin 1735 1730 1549 1454 - noflags 1236526247,367664 3289,390208
477,843140 -kse- 1001 1001 1001,1001,1001,0,20,68,69,1004 -
g1-35(6.4-S)[2]
So above-listed items would be:
* firefox-bin
* 1735
...
* 1236526247,367664
* 3289,390208
* 477,843140
* -kse-
* -kse-
....
Granted, not every machine will necessarily have PROCFS in the
kernel configuration, but it is in GENERIC.
