ConnectNamedPipe不响应客户端的连接 [英] ConnectNamedPipe does not react to client's connection

问题描述

大家好，

我调用CreateNamedPipe来指定重叠模式，然后创建一个事件并将其放入OVERLAPPED结构中.然后，我分叉到另一个线程，在那儿我调用ConnectNamedPipe并等待使用WaitForSingleObject的连接事件.它阻塞了一个线程 但是在另一个进程中调用CreateFile后，它不会返回线程.

I call CreateNamedPipe specifying an overlapped mode, then I create an event and put it into OVERLAPPED structure. Then I fork to another thread and there I call ConnectNamedPipe and wait for a connection event using WaitForSingleObject. It blocks a thread but it does not return to thread after I call CreateFile at another process.

服务器代码:

 

OVERLAPPED ovlGlobal;
HANDLE hPipeGlobal;

unsigned
 long
 int
 __stdcall ConnectNamedPipeThreadProc(void
 *parameter){
 ovlGlobal.hEvent = CreateEvent(NULL,TRUE,FALSE,NULL);
 ConnectNamedPipe(hPipeGlobal,&ovlGlobal);
 WaitForSingleObject(ovlGlobal.hEvent,INFINITE);
 /* here is a call to ReadFileEx */

}

void
 CreateButtonClick(){
 wchar_t
 pipepath[600]=L"\\\\.\\pipe\\123123"
;

 hPipeGlobal = CreateNamedPipe(pipepath,
 PIPE_ACCESS_DUPLEX|FILE_FLAG_FIRST_PIPE_INSTANCE|FILE_FLAG_OVERLAPPED,
 PIPE_TYPE_MESSAGE|PIPE_NOWAIT,
 PIPE_UNLIMITED_INSTANCES,
 64*1024,
 64*1024,
 60*1000,
 NULL);
 CreateThread(NULL,0,ConnectNamedPipeThreadProc,NULL,0,NULL);
}
