Process-Id Discovery

Sunderjeet Singh — Fri, 30 Mar 2007 05:56:52 GMT

Hi,

What are possible options of process-id discovery in HP-UX 11i (except ps)? I want to discover the process-ids of some set of processes in the system from within a C program. Does HP-UX has something similar to Linux /proc filesystem.

thanks

Hi,
You can use the lsof tool to find the opened file on the system by any processes.

U can download the depot from;

Unfortunately, HP-UX doesn't come with a /proc virtual filesystem.
I also haven't heard of a patch that would supply this feature.
If you want to access process data programatically you could use the pstat() syscall.
In man 2 pstat the struct is explained, and there's even an example code snippet.
