Question

windows下的C语言socket编程没有相关socket的头文件怎么办？

Answer 1

//服务端代码
#include<winsock2.h>
#include<stdio.h>
#pragma comment(lib,"ws2_32.lib")//这句关键;
void main(){
WORD wV;
WSADATA ws;
int er;
wV=MAKEWORD(1,1);
er=WSAStartup(wV,&ws);
if(er!=0){
return;

}
if(LOBYTE(ws.wVersion)!=1||HIBYTE(ws.wVersion)!=1){
WSACleanup();
return;
}
SOCKET sockSrv=socket(AF_INET,SOCK_STREAM,0);
SOCKADDR_IN addrSrv;
addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY);
addrSrv.sin_family=AF_INET;
addrSrv.sin_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];
sprintf(sendBuf,"welcome %s to wozhe",inet_ntoa(addrClient.sin_addr));
send(sockConn,sendBuf,strlen(sendBuf)+1,0);
char recvBuf[100];
recv(sockConn,recvBuf,100,0);
printf("%s\n",recvBuf);
closesocket(sockConn);
}
}
