用C或者C++語言實現SOCKET通信

#include

#include

void main()

{

WORDwVersionRequested;

WSADATA wsaData;

int err;

wVersionRequested = MAKEWORD(1,1);

err = WSAStartup(wVersionRequested,&wsaData);

if( err != 0)

{

return;

}

if(LOBYTE( sion ) != 1||

HIBYTE( sion) != 1)

{

WSACleanup();

return;

}

SOCKET sockSrv=socket(AF_INET,SOCK_STREAM,0);

SOCKADDR_IN addrSrv;

_addr.S_un.S_addr=htonl(INADDR_ANY);

_family=AF_INET;

_port=htons(6000);

bind(sockSrv,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR));

listen(sockSrv,5);

SOCKADDR_IN addrClient;

int len=sizeof(SOCKADDR);

while(1)

{

SOCKET sockConn=accept(sockSrv,(SOCKADDR*)&addrClient,&len);

char sendBuf[100];

sprint(sendBuf,”Welcome %s to “,

inet_ntoa(_addr));

send(sockConn,sendBuf,strlen(sendBuf)+1,0);

char recvBuf[100];

recv(sockConn,recvBuf);

printf(“%sn”,recvBuf);

closesocket(sockConn);

WSACleanup();

}

}

注：這是Server端;File->New->Win32 Console Application，工程名：TcpSrv;然後，File->New->C++ Source File，文件名：TcpSrv;在該工程的Setting的Link的ct/library modules項要加入ws2_
