pQueryPerformanceFrequency

This global variable is optional and should be set for platforms that provide timer functions with higher granularity than GetTickCount. The OAL initializes pQueryPerformanceFrequency to point to OEMQueryPerformanceFrequency, if defined.

  BOOL (*pQueryPerformanceFrequency)(LARGE_INTEGER *lpPerformanceCount);

Remarks

Windows CE provides a default implementation of QueryPerformanceFrequency, which is based on GetTickCount, but will call pQueryPerformanceFrequency if defined.
