you might want to try out libstatgrab, it should be able to give you unified access to that information on many different operating systems. It will still open /proc on GNU/Linux, but you won't know.

You can read all information from /proc/<process pid>/. I guess the file cmdline and the link exe in each of these directories will be relevant for you.

There is no other way to read the list, /proc exists for this purpose. The simplest way to find out exactly how to do this job would be to read the source for procps, which may include a library to do most of the work for you.
