LPC通信连接建立成功后NtReplyPort失败

[yjip267]

LPC通信连接建立成功后,客户进程向服务进程发送消息NtReplyPort失败 错误值0xc000000d，就两个参数。不知道哪里错误了。

服务代码：

//定义并填充结构体

//创建LPC server port
status = pThis->meNtCreatePort(&hserverPort, &oa, TLPC_MAX_MSG_DATA_LENGTH,sizeof(TLPC_PORTMSG), 0);
if (!NT_SUCCESS(status)) { OutputDebugString("NtCreatePort fail\r\n");break; }

GetLastError();这个没用。 这里用的未公开的API。所以这个获取不到。错误值0xc000000d，说的是参数问题。但是不知道参数哪里有问题。
