用iocpsocket源码，谁能帮助一下(50)

用iocpsocket源码，谁能帮助一下，我在网上找到一个，但是还是不能安装，也不能使用，谁能有好使的iocp，给我帮个忙啊

网上找得到的代码都很有问题的，不用试了。

听说DXSOCKET不错

csnd 上有一个去那里看看吧！ 那个应该不错的！

都卖钱了!

我已不用DELPHI了,这是我学习C++ IOCP的源码// Module Name: iocmplt.cpp//// Description://// This sample illustrates how to develop a simple echo server Winsock// application using the completeion port I/O model. This // sample is implemented as a console-style application and simply prints// messages when connections are established and removed from the server.// The application listens for TCP connections on port 5150 and accepts them// as they arrive. When this application receives data from a client, it// simply echos (this is why we call it an echo server) the data back in// it's original form until the client closes the connection.//// Compile://// cl -o iocmplt iocmplt.cpp ws2_32.lib//// Command Line Options://// iocmplt.exe //// Note: There are no command line options for this sample.#include <winsock2.h>#include <windows.h>#include <stdio.h>#define PORT 5150#define DATA_BUFSIZE 8192typedef struct{ OVERLAPPED Overlapped; WSABUF DataBuf; CHAR Buffer[DATA_BUFSIZE]; DWORD BytesSEND; DWORD BytesRECV;} PER_IO_OPERATION_DATA, * LPPER_IO_OPERATION_DATA;typedef struct { SOCKET Socket;} PER_HANDLE_DATA, * LPPER_HANDLE_DATA;DWORD WINAPI ServerWorkerThread(LPVOID CompletionPortID);void main(void){ SOCKADDR_IN InternetAddr; SOCKET Listen; SOCKET Accept; HANDLE CompletionPort; SYSTEM_INFO SystemInfo; LPPER_HANDLE_DATA PerHandleData; LPPER_IO_OPERATION_DATA PerIoData; int i; DWORD RecvBytes; DWORD Flags; DWORD ThreadID; WSADATA wsaData; DWORD Ret; if ((Ret = WSAStartup(0x0202, &wsaData)) != 0) { printf("WSAStartup failed with error %d/n", Ret); return; } // Setup an I/O completion port. if ((CompletionPort = CreateIoCompletionPort(INVALID_HANDLE_VALUE, NULL, 0, 0)) == NULL) { printf( "CreateIoCompletionPort failed with error: %d/n", GetLastError()); return; } // Determine how many processors are on the system.
