Subj : PerfView API

Hello All,

Does anybody know the details? All I found are COM.SYS and PRINT0x.SYS sources. 
This is an interface similiar to DosTmrQueryFreq, DosTmrQueryTime and 
DosRegisterPerfCtrs. But IMHO TmrQueryFreq and TmrQueryTime are for 
applications only. I can't find any details about RegisterPerfCtrs. I can study 
COM & PRINT sources, but it would be preffered to have a small doc or a brief 
explanation.

The second question is about TIMER0.SYS. Can PIT manipulations affect PerfView 
accuracy? AFAIK it is based on the same timer channel 0.

Cheers,
\Lesha
