sendto

基本解释

Use the SendTo method to send datagrams to a remote host.
使用SendTo方法可将数据报发送到远程主机。
You can also establish a default remote host for a connectionless protocol prior to calling the SendTo method.
您也可以在调用SendTo方法之前,为无连接协议建立默认远程主机。
Although intended for connectionless protocols, SendTo also works with connection-oriented protocols.
虽然SendTo用于无连接协议,但它同样适用于面向连接的协议。
If you are using a connectionless protocol, you do not need to establish a default remote host with the Connect method prior to calling SendTo.
如果您使用的是无连接协议,则在调用SendTo之前,不需要使用Connect方法建立默认远程主机。
A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.
由于套接字没有连接并且(当使用一个sendto调用发送数据报套接字时)没有提供地址,发送或接收数据的请求没有被接受。
