一个基本的socket程序，找本参考书看看吧！#include <winsock2.h>DWORD ClientThread(LPVOID lpParam)
{
SOCKET sock = (SOCKET)lpParam;
char szBuf[DEFAULT_BUFFER];
char szBuf2[] = "1038  1234567892          000000200101";
int nRet, nLeft, idx; while(1)
{
nRet = recv(sock,szBuf,DEFAULT_BUFFER,0);
if(nRet == 0)
break;
else if(nRet == SOCKET_ERROR)
{
printf("recv failed: %d\n",WSAGetLastError());
break;
}
szBuf[nRet] = '\0';
printf("RECV: %s\n",szBuf);
if(!bRecvOnly)
{
nLeft = nRet;
idx = 0;
while(nLeft > 0)
{
nRet = send(sock, &szBuf2[idx], nLeft,0);
if(nRet == 0)
break;
else if(nRet ==SOCKET_ERROR)
{
printf("send() failed: %d\n",WSAGetLastError());
break;
}
nLeft -= nRet;
idx += nRet;
}
}
printf("SEND: %s\n", szBuf2);
}
return 0;
}int main(int argc, char **argv)
{
WSADATA wsd;
SOCKET sListen,
sClient;
int iAddrSize;
HANDLE hThread;
DWORD dwThreadID;
struct sockaddr_in local,
client;
if(WSAStartup(MAKEWORD(2,2), &wsd) != 0)
{
printf("failed to load Winsock!\n");
return 1;
} sListen = socket(AF_INET,SOCK_STREAM,IPPROTO_IP);
if(sListen == SOCKET_ERROR)
{
printf("socket() failed: %d \n",WSAGetLastError());
return 1;
} local.sin_family = AF_INET;
local.sin_port = htons(iPort);
local.sin_addr.s_addr = inet_addr(szAddress);
if(local.sin_addr.s_addr == INADDR_NONE)
{
Usage();
}
else
local.sin_addr.s_addr = htonl(INADDR_ANY); if(bind(sListen,(struct sockaddr*)&local,sizeof(local)) == SOCKET_ERROR)
{
printf("bind() failed : %d \n", WSAGetLastError());
return 1;
} printf("start listening on %s:%d...\n",inet_ntoa(local.sin_addr),ntohs(local.sin_port));
listen(sListen, 8); while(1)
{
iAddrSize = sizeof(client);
sClient = accept(sListen, (struct sockaddr*)&client,&iAddrSize);
if(sClient == INVALID_SOCKET)
{
printf("accept() failed: %d \n",WSAGetLastError());
break;
}
printf("accepted client: %s:%d\n",inet_ntoa(client.sin_addr),
ntohs(client.sin_port)); hThread = (LPVOID)_beginthread(ClientThread,0,(LPVOID)sClient); if(hThread == NULL)
{
printf("CreateThread() failed: %d\n",WSAGetLastError());
break;
}
CloseHandle(hThread);
}
closesocket(sListen); WSACleanup();
return 0;
}
