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