目前还不完全清楚你在问什么。 Google 搜索 sendto 和 EWOULDBLOCK 意味着它可以被返回，是的。理论上，套接字上的任何发送操作都可能耗尽发送缓冲区空间，这意味着操作系统必须等待，直到此类空间可用，因此 EWOULDBLOCK 是为非阻塞套接字返回的合理值。
It's not entirely clear what you're asking. A Google search for sendto and EWOULDBLOCK would imply that it can be returned, yes. Any sending operation on a socket could theoretically run out of send-buffer space, which means the operating system would have to wait until such space became available, hence EWOULDBLOCK is a reasonable value to return for a non-blocking socket.
