Re: [LIP] How to get the parent PID.

getppid() returns the parent PID of the current process.

You can also check PPID in the process's environment.

Both the above will work only for the current process. If you want to
find the PPID of another process, the Linux-specific way is to look at
the fourth word in /proc/PID/environ.
