 C: 
 Write sockets on Windows with Codeblocks to import sockets, import libws2_32.a and libwsock32.a in Complier 

The code is as follows:

#include <winsock2.h>

#pragma comment (lib, "Ws2_32.lib") #导入库

void Socket_function () {
Wsadata WSD;
struct sockaddr_in dest;
Char buf[400];
Char sendbuf[400];
WSAStartup (Makeword (2, 2), &WSD); #加载库
Socket socketfd= socket (af_inet, sock_stream,ipproto_tcp);
Dest.sin_family=af_inet;
Dest.sin_port=htons (21567);
DEST.SIN_ADDR.S_ADDR=INET_ADDR ("192.168.56.1");
memset (& (Dest.sin_zero), 0,sizeof (struct sockaddr_in));
if (Connect (socketfd, struct sockaddr*) &dest,sizeof (struct sockaddr_in)) = =-1) {
printf ("Failed%d\n", WSAGetLastError ());
}
while (1) {
printf ("Connect success\n");
Recv (socketfd,buf,1024,0);
printf ("buf=%s\n", buf);
strcpy (SendBuf, "MSG1");
printf ("Please input the msg:\n");
scanf ("%s", sendbuf);
Send (Socketfd,sendbuf,strlen (SENDBUF), 0);
}
Closesocket (SOCKETFD);
WSACleanup ();
