All the files and sources you have uploaded here are from the RivaTuner-
SDK. With them you can create a Plugin-
DLL for Rivatuner. Of course we can see some interesting calls here - but the routines are INSIDE of RivaTuner.EXE (and thus exported from there). You WILL need RivaTuner running on the system to get these things working (or the source of RT, which is not available AFAIK).
I'm the founder of STLCD, a fairly well known LCD-Software here in Germany. And I'm looking for the same infos about ATI-Cards like you -
for two years now. I know what I'm talking about, there will be no more information to find.
