ps_ppid() returns the parent pid, ps_parent() returns a ps_handle of the parent.

Usage
ps_ppid(p)

ps_parent(p)

Arguments
p

Details

On POSIX systems, if the parent process terminates, another process (typically the pid 1 process) is marked as parent. ps_ppid() and ps_parent() will return this process then.

Both ps_ppid() and ps_parent() work for zombie processes.

Value

ps_ppid() returns and integer scalar, the pid of the parent of p. ps_parent() returns a ps_handle.
