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.
