Network provider question

hi there,

I was wondering whether there was any information apart
from Windows 98 DDK, on how to implement a network
provider DLL for Windows 98. In particular, I'm after
detailed explanation of the API routines (such as NPLogon,
NPLogoff, NPGetCapts etc). I've had a look at the DDK, and
while there are basic information bits there, including a
very simple sample, seems hardly sufficient in my case.
Googling doesn't seem to be helping too much either,
considering 98 is fading into the background much too fast.

thanks in advance,

regards,
Greg
