Does MASM support the WINAPI QueryThreadCycleTime ?

  I can't seem to find it in .inc, .lib, etc.

  GetThreadTimes works great and helps to explain batch response time,
matches PROCMONs' 'Thread Exit' times, GetTickCount, and GetLocalTime,
but all are Wall-Clock times.

  QueryThreadCycleTime appears to be CPUR (real) in the IBM M/F world,
which helps to see more "absolute" (non-interference) and "average" times
to determine if any coding tuning actually helps...

It's Vista upwards. If that isn't a problem, link to it dynamically (Kernel32.dll).

...or use Michael's timing macros (which use RDTSC)

Is that function wrapper of NtQueryInformationThread from ntdll.dll with ThreadInformationClass of ThreadCycleTime ?

  Thankx for the NT info and dynamic CALL suggestion; those, w/GetVersionEx & DUMPBIN, works great.
