= Description
A Ruby interface to the 'ps' command. This is a C extension, not parsed
output. For BSD flavors the kvm interface is used.
= Synopsis
require 'sys/proctable'
include Sys
# Everything{ |p|
puts p.comm
# Just one process
p =
puts p.comm
# Return the results as an array of ProcTableStructs
a =
a.each do |p|
= Constants
Returns the current version number for this library (as a string).
= Class Methods
Returns an array of fields available on the current OS. = nil){ |s| ... }
If no pid's or processes are included as arguments, in block form it
returns a struct of type ProcTableStruct for every process in the proc
table. Otherwise it returns an array of ProcTableStruct's.
If a pid argument is provided, a single ProcTable struct is returned, or
nil if the pid is not found.
= Exception Classes
ProcTable::Error < StandardError
Raised if any of the ProcTable methods fail.
= Supported fields
You can view the supported fields with the "fields()" class method.
= Future Plans
Add a pure-ruby version as an alternative
Add ttydev info
Add a sysctl version
= Known Bugs
The kvm version for FreeBSD 5.x does not support all of the fields that
the 4.x version supports.
