I need a C/C++ API that allows me to list the running processes on a Linux system, and list the files each process has open.
I do not want to end up reading the /proc/ file system directly.
Can anyone think of a way to do this?

Open the terminal window on Linux. For remote Linux server use the ssh command for log in purpose. Type the ps aux to see all running process in Linux. Alternatively, you can issue the top command or htop command to view running process in Linux.
To list currently running processes, use the ps , top , htop , and atop Linux commands. You can also combine the ps command with the pgrep command to identify individual processes.
You need to use the ps command. It provides information about the currently running processes, including their process identification numbers (PIDs). Both Linux and UNIX support the ps command to display information about all running process.
To see only the processes owned by a specific user on Linux run: ps -u {USERNAME} Search for a Linux process by name run: pgrep -u {USERNAME} {processName} Another option to list processes by name is to run either top -U {userName} or htop -u {userName} commands.

Is the source of ps and other process tools. They do indeed use proc (indicating it is probably the conventional and best way). Their source is quite readable. The file
/procps-3.2.8/proc/readproc.c May be useful. Also a useful suggestion as posted by ephemient is linking to the API provided by libproc, which should be available in your repo (or already installed I would say) but you will need the "-dev" variation for the headers and what-not.
Good Luck
