Hi Woonyong, Which Windows operating system are you working with? Probably Windows XP or older because the WSAPoll function is only included in Windows Vista and later. I plan to replace it with a select function soon so that ROSWIN32 can be used on Windows XP as well but for now it only works with Windows Vista or Windows 7.
