Device driver

Hi,

I am writing a program to install “Client for Microsoft”, “Dial up adapter”.
( If they are allready installed you can see them in control
panel/networking). I have came across few APIs SetupDiCallClassInstaller,
SetupDiCreateDeviceInfo etc in MSDN/DDK documentation. But I have not came
across any where to start and how to start. Can anybody tell or suggest how
to write a devie driver. Anybody have an idea where can I get more
information about writing device drivers.

Thanks,
