Query the parent processes recursively, up to the first process. (On some platforms, like Windows, the process tree is not a tree and may contain loops, in which case ps_descent() only goes up until the first repetition.)

Usage

ps_descent(p = ps_handle())

Arguments

p

Process handle.

Value

A list of process handles, starting with p, each one is the parent process of the previous one.
