PERF_MEM_FREE callback function (perflib.h)

  • Article

Providers implement this function to provide custom memory management for PERFLIB. PERFLIB calls this callback when it needs to free memory that it allocated using AllocateMemory.

The PERF_MEM_FREE type defines a pointer to this callback function. The FreeMemory function is a placeholder for the application-defined function name.

Syntax

PERF_MEM_FREE PerfMemFree;

void PerfMemFree(
  [in] LPVOID pBuffer,
  [in] LPVOID pContext
)
{...}

Parameters

[in] pBuffer

Memory to free.

[in] pContext

Context information set in the pMemContext member of PERF_PROVIDER_CONTEXT.

Return value

None

Remarks

If you used the -MemoryRoutines when calling CTRPP, you must implement this callback function. You pass the name of your callback function to CounterInitialize.

Windows Vista:  The CounterInitialize function is named PerfAutoInitialize.
