1/5/2010

This function is optional and should be set for platforms that provide timer functions with higher granularity than GetTickCount.

The OAL initializes pQueryPerformanceCounter to point to OEMQueryPerformanceCounter, if defined.

Syntax

extern BOOL (*pQueryPerformanceCounter)(
  LARGE_INTEGER* lpPerformanceCount
);

Parameters

  • lpPerformanceCount
    [in] Pointer to the performance count.

Return Value

This function should always return TRUE.

Remarks

Windows Embedded CE provides a default implementation of QueryPerformanceCounter, which is based on GetTickCount, but will call pQueryPerformanceCounter if defined.

Library coredll.lib
Windows Embedded CE Windows CE 2.10 and later
