无法使用带有DCE管道的异步RPC将数据推送到服务器

Question

我想使用带管道的异步RPC将数据推送到服务器。这是我的代码：

//file: Xasyncpipe.idl:   
interface IMyAsyncPipe
{
//define the pipe type
typedef pipe int ASYNC_INTPIPE;

int MyAsyncInputPipe(
    handle_t hBinding, 
    [in] ASYNC_INTPIPE *inpipe) ;
};



//file:Xasyncpipe.acf:
interface IMyAsyncPipe
{
[async] MyAsyncInputPipe () ;
} ;



//file:Client.cpp
mian()
{
// Creates a binding handle.
...
RPC_ASYNC_STATE Async;
status = RpcAsyncInitializeHandle(&Async, sizeof(RPC_ASYNC_STATE));
Async.UserInfo = NULL;
Async.NotificationType = RpcNotificationTypeIoc;
Async.u.IOC.hIOPort = CreateIoCompletionPort(INVALID_HANDLE_VALUE, NULL, 0, 0);
ASYNC_INTPIPE inputPipe;

// Calls the RPC function.
MyAsyncInputPipe(&Async, hBinding, &inputPipe);
}



//file:Server.cpp
void MyAsyncInputPipe(PRPC_ASYNC_STATE state, handle_t hBinding, ASYNC_INTPIPE *pipe)
{
std::cout << "Input Test" << std::endl;
}

我在函数MyAsyncInputPipe中添加了断点，并且永远不会触发断点。

我将Xasyncpipe.idl从[in] ASYNC_INTPIPE *inpipe更改为[out] ASYNC_INTPIPE *inpipe，触发了断点。

有谁知道原因？

在客户端管道推送终端信号之前，服务器不会接收数据。

//push terminal signal    
inputPipe.push(inputPipe.state, NULL, 0);
