= Description
A Ruby interface for gathering process table information. This is a pure
Ruby implementation that reads data out of your /proc filesystem.
= Synopsis
require 'sys/proctable'
include Sys
# Everything
ProcTable.ps{ |p|
puts p.pid.to_s
puts p.comm
...
}
or
# Just one process
p = ProcTable.ps(2123)
puts p.pid.to_s
puts p.comm
...
or
# Return the results as an array of ProcTableStructs
a = ProcTable.ps()
a.each do |p|
puts a.pid
...
end
= Constants
VERSION
Returns the current version number for this library (as a string).
= Class Methods
ProcTable.fields
Returns an array of fields available on the current OS.
ProcTable.ps(pid=nil)
ProcTable.ps{ |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 process id is provided, a single ProcTable struct is returned, or
nil if the pid is not found.
= Exception Classes
ProcTable::Error < StandardError
Raised if the /proc field is unreadable and/or unmounted.
= Supported fields
You can view the supported fields with the "fields()" class method.
