我遇到了让winsock RIO工作的问题。 似乎每次发布RIOReceive时它都会立即返回0字节,并且我的同伴无法收到消息。
在发布RIOReceive之后,我等待RIODequeCompletion,它立即使用numResults = 1进行deques,但是当我检查RIORESULT结构的bytesTransferred时,它是0.这告诉我,我不是正确设置这个东西,但我找不到文档或示例告诉我还应该做些什么。
互联网上的RIO似乎很少。我查看了MSDN,Len Holgate with TheServerFramework,此网站和两个GitHub RIO服务器。
RIOEchoServer和RIOServer_sm9在GitHub上,但我不能发布两个以上的链接(这是我在这个网站上的第一个问题)。
此代码只是为了证明事情。它目前没有设置使用sendCQ,没有很好地处理错误等...
这是准备工作:
void serverRequestThread() {
//init buffers
//register big buffers
recvBufferMain = rio.RIORegisterBuffer(pRecvBufferMain, bufferSize);
sendBufferMain = rio.RIORegisterBuffer(pSendBufferMain, bufferSize);
if (recvBufferMain == RIO_INVALID_BUFFERID) {
cout << "RIO_INVALID_BUFFERID" << endl;
}
if (sendBufferMain == RIO_INVALID_BUFFERID) {
cout << "RIO_INVALID_BUFFERID" << endl;
}
//create recv buffer slice
recvBuffer1.BufferId = recvBufferMain;
recvBuffer1.Offset = 0;
recvBuffer1.Length = 10000;
//create send buffer slice
sendBuffer1.BufferId = sendBufferMain;
sendBuffer1.Offset = 0;
sendBuffer1.Length = 10000;
//completion queue
recvCQ = rio.RIOCreateCompletionQueue(CQsize, NULL);
sendCQ = rio.RIOCreateCompletionQueue(CQsize, NULL);
if (recvCQ == RIO_INVALID_CQ) {
cout << "RIO_INVALID_CQ" << endl;
}
if (sendCQ == RIO_INVALID_CQ) {
cout << "RIO_INVALID_CQ" << endl;
}
//start a loop for newly accept'd socket
while (recvCQ != RIO_INVALID_CQ && sendCQ != RIO_INVALID_CQ) {
//get accept'd socket
struct sockaddr_in saClient;
int iClientSize = sizeof(saClient);
acceptSocket = accept(listenSocket, (SOCKADDR*)&saClient, &iClientSize);
if (acceptSocket == INVALID_SOCKET) {
cout << "Invalid socket" << endl;
printError();
}
//register request queue
requestQueue = rio.RIOCreateRequestQueue(
acceptSocket, //socket
10, //max RECVs on queue
1, //max recv buffers, set to 1
10, //max outstanding sends
1, //max send buffers, set to 1
recvCQ, //recv queue
recvCQ, //send queue
pOperationContext //socket context
);
if (requestQueue == RIO_INVALID_RQ) {
cout << "RIO_INVALID_RQ" << endl;
printError();
}
我现在发布一个RIOReceive:
//start a loop to repin recv buffer for socket
while (acceptSocket != INVALID_SOCKET) {
//pin a recv buffer to wait on data
recvSuccess = rio.RIOReceive(
requestQueue, //socketQueue
&recvBuffer1, //buffer slice
1, //set to 1
RIO_MSG_WAITALL, //flags
0); //requestContext
if (recvSuccess == false) {
cout << "RECV ERROR!!!!!!!!\n";
printError();
}
//wait for recv to post in queue
//std::this_thread::sleep_for(std::chrono::milliseconds(3000));
一旦我调用RIODequeCompletion,它就会返回1:
numResults = 0;
while (numResults == 0) numResults = rio.RIODequeueCompletion(recvCQ, recvArray, 10);
if (numResults == RIO_CORRUPT_CQ) {
cout << "RIO_CORRUPT_CQ" << endl;
} else if (numResults == 0) {
cout << "no messages on queue\n";
} else if (numResults > 0) {
但是当我检查RIORESULT的bytesTransferred时,它始终为0:
if (recvArray[0].BytesTransferred > 0) {
//process results
if (pRecvBufferMain[0] == 'G') {
//set respnose html
strcpy(pSendBufferMain, responseHTTP);
sendSuccess = rio.RIOSend(
requestQueue, //socketQueue
&sendBuffer1, //buffer slice
1, //set to 1
0, //flags
0); //requestContext
} else if (pRecvBufferMain[0] == 'P') {
//process post
} else {
//recv'd a bad message
}
} //end bytesTransferred if statement
//reset everything and post another recv
}//end response if statement
std::this_thread::sleep_for(std::chrono::milliseconds(100));
}//end while loop for recv'ing
std::this_thread::sleep_for(std::chrono::milliseconds(100));
}//end while loop for accept'ing
}// end function
就像我说的那样,我可能没有正确使用RIOReceive,和/或我没有设置我需要的正确套接字选项(现在没有)。
我感谢任何帮助。

尝试删除RIO_MSG_WAITALL
。可能存在一个错误,您只能获得关闭通知(字节== 0),而不是使用其中的数据完成。无论哪种方式,看看代码是否在没有标志的情况下工作会很有趣。
我的示例服务器和测试是否适用于您的硬件?

在使用RioReceive和RioNotify以及RioDequeueCompletion时,我遇到了类似的问题,即我的出队完成结果中有零bytesReceived。我还会在出列的完成结果中看到WSAEINVAL(无效参数= 10022)的“状态”值,这似乎表明接收调用的WSA错误代码。
我遇到错误的特殊原因是因为我为receiveBuffer分配了内存而我试图将缓冲区指针作为我的缓冲区句柄传递给RioReceive的RIO_BUFFER_SEGMENT而不是传递 RioRegisterBuffer返回的IntPtr 。
我完全责怪自己使用太多无类型的IntPtrs并丢失类型检查。 :)
