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).
