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).
