require 'libcgroup'
puts LibCgroup.cgroup_init
puts root = LibCgroup.cgroup_new_cgroup("/")
puts LibCgroup.cgroup_get_cgroup(root)
puts ctl = LibCgroup.cgroup_get_controller(root, "cpu")
(0..(LibCgroup.cgroup_get_value_name_count(ctl)-1)).each do |i|
name = LibCgroup.cgroup_get_value_name(ctl, i)
s = FFI::MemoryPointer.new :pointer, 1
LibCgroup.cgroup_get_value_string(ctl, name, s)
strPtr = s.read_pointer
if strPtr.null?
puts name
else
puts "#{name} #{strPtr.read_string}"
end
