Get given process name and ppid programmatically

Question

On Linux and other POSIX (?) operating systems - how to get name and parent pid of given (by pid) process? Currently I'm reading /proc but OSX doesn't have it. On OSX I'm using libproc but that doesn't work on Linux:

int ret = proc_pidpath (pid, pathbuf, sizeof(pathbuf));
if ( ret <= 0 ) {
    _dbg("   %s\n", strerror(errno));
    return false;
}

may be you need [getppid()](http://linux.die.net/man/3/getppid)? — Sourav Ghosh, Aug 21 '15 at 07:45

Unfortunately, when it comes to process info, every OS does things differently. If you only need to know about user-launched apps, look into the NSWorkspace class's runningApplicationWithProcessIdentifier: method. Otherwise, you'll have to use a platform-specific sysctl as described here:
