Retrieves the performance values contained in the PERFORMANCE_INFORMATION structure.

Syntax

BOOL WINAPI GetPerformanceInfo(
  __out  PPERFORMANCE_INFORMATION pPerformanceInformation,
  __in   DWORD cb
);

Parameters

pPerformanceInformation [out]

A pointer to a PERFORMANCE_INFORMATION structure that receives the performance information.

cb [in]

The size of the PERFORMANCE_INFORMATION structure, in bytes.

Return Value

If the function succeeds, the return value is TRUE. If the function fails, the return value is FALSE. To get extended error information, call GetLastError.

Remarks

Starting with PSAPI version 2 for Windows 7 and Windows Server 2008 R2, this function is defined as K32GetPerformanceInfo in Psapi.h and exported in Kernel32.lib and Kernel32.dll. However, you should always call this function as GetPerformanceInfo. To ensure correct resolution of symbols for programs that will run on earlier versions of Windows, add Psapi.lib to the TARGETLIBS macro and compile the program with –DPSAPI_VERSION=1.
