本文介绍了一个C++实现的ComFriendlyWaitMtaThreadProc函数，该函数通过CoInitializeEx初始化COM环境，并创建了ComFriendlyWaiter实例。接着通过CoMarshalInterThreadInterfaceInStream将实例传递到另一个线程，最后释放资源并等待事件。

c++代码（大体逻辑没问题，细节需要确认）

DWORD __stdcall *ComFriendlyWaitMtaThreadProc(LPVOID lpThreadParameter)
{
CoInitializeEx(0,0);
ThreadParam* pParam =(ThreadParam*)lpThreadParameter;
ComFriendlyWaiter* pData =newComFriendlyWaiter(pParam->p2, pParam->p1);
hr =CoMarshalInterThreadInterfaceInStream(GUID_6d5140c1_7436_11ce_8034_00aa006009fa, pData,&pStream);
pData->Release();
SetEvent(pParam->hEvent);
WaitForSingleObject(pParam->hXXX);
CoUninitialize();
}
