/proc on HP-UX?

[Ioana Sundius]

Can't seem to find any reference to the process file system format in the man pages / reference books from HP.

Does anyone know if they are implemented? They are the standard way an application can obtain information on currently running processes. Linux, Solaris, AIX all implement it -- what about HP?

If there is indeed no /proc on HP, then what is the preferred way to obtain the start time of a process currently running with a given pid?
--> long getProcessStartTime(int pid);

Thanks!

HP-UX does not have a /proc filesystem.

Variations of the pstat() system call will do what you want? Man 2 pstat for details.

Hi Ioana:

There is a good white paper, with examples, on 'pstat()' here:

http://docs.hp.com/hpux/onlinedocs/os/11i/pstat_whitepaper.pdf

As noted in the paper, the 'lsof' utility utilizes this interface and is, in fact, a good source of further examples since its source code is freely available.

Regards!

Thank you, Clay -- that seems to do the trick quite easily:-)
