NAME
Proc::Find::Parents - Find parents of a process (up to the root)
VERSION
This document describes version 0.631 of Proc::Find::Parents (from Perl
distribution Proc-Find-Parents), released on 2018-01-17.
SYNOPSIS
FUNCTIONS
None are exported by default, but they are exportable.
get_parent_processes($pid[, \%opts]) => ARRAY
Return an array containing information about parent processes of $pid up
to the parent of all processes (usually "init"). If $pid is not
mentioned, it defaults to $$. The immediate parent is in the first
element of array, followed by its parent, and so on. For example:
[{name=>"perl",pid=>13134}, {name=>"konsole",pid=>2232}, {name=>"init",pid=>1}]
Currently retrieves information by calling pstree program. Return undef
on failure.
Known options:
* method => STR (default: "proctable")
Either "proctable" (the default, which means to use
Proc::ProcessTable) or "pstree" (which uses the pstree command,
which might not be portable between Unices).

names not truncated by "pstree", works on Windows. Cons: a little bit
more heavyweight (uses File::Spec, Cwd, File::Find).
