Here is a modified code:
-------------------------------------------------------------------------
require 'Win32API'

WH_MSGFILTER = -1
hook = Win32API.new('user32','SetWindowsHookEx', 'ILLL', 'L')
library = Win32API.new('kernel32','LoadLibrary', 'P', 'L')
procadr = Win32API.new('kernel32','GetProcAddress', 'LP', 'L')

lcall = library.call('mylibrary.dll')
pcall = procadr.call(lcall, 'funcname')

hook.call(WH_MSGFILTER,pcall,lcall,0)
-------------------------------------------------------------------------
