send是TCP通信的发送方法,在send之前保证建立了socket通信连接,socket中记录了与之连接的对方的地址,所以可以说是第一个参数SOCKET记录了要发往的地址;注:TCP套接字只能进行一对一的通信,所以不需要地址再来进行目的地的标识,套接字就可以确定要发往的方向;
SOCKET Sock;
Sock=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
connect(Sock,。。。。。。。);
char *buf;
send(Sock,buf,strlen(buf),0);
其中就是Sock记录的你要发往的目的地;
只有UDP通信才要写入对方地址,UDP套接可以进行多对多的通信,所以在发送的时候要写入对方地址;
UDP调用sendto()方法;可以查看MSDN
