One word: procfs

I don't know how you plan to identify the process: by program name,
process id., parent process id., or running as a specific userid.

Whatever you choose, you scan /proc and its subdirectories to see
everything else that is running in userspace under Linux. All the
entries can be treated as text files of directories.
