int main() {
int so=socket(AF_INET,SOCK_STREAM,0),r;
sockaddr_in addr;
hostent hp;
hp=gethostbyname("www.csdn.net");
addr.sin_addr.s_addr=((unsigned long*)hp->h_addr);
addr.sin_family=AF_INET;
addr.sin_port=htons(80);
connect(so,(sockaddr*)&addr,sizeof(sockaddr));
char message[200]="GET / HTTP/1.0\r\nHost:www.csdn.net\r\n\r\n";
send(so,message,strlen(message)+1,0);
char buf[1024]={0};
while(recv(so,buf,1024,MSG_PEEK)){
puts(buf);
memset(buf,0,1024);
}
}
就这样一直收不完，请问为什么
谢谢

Please Don't use "MSG_PEEK",If you use it ,you will recv the same message !!!
