pQueryPerformanceFrequency

  • 项目

This function 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
);

Return Values

This function should always return TRUE.

Remarks

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

Requirements

OS Versions: Windows CE 2.10 and later.
Header: Developer-defined.
Link Library: Developer-defined.
