CAsyncSocket会将socket设置为非阻塞的，所以send返回10035是正常的，看msdn上说的：
This error is returned from operations on nonblocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket. It is a nonfatal error, and the operation should be retried later. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connect on a nonblocking SOCK_STREAM socket, since some time must elapse for the connection to be established.
你应该在FD_WRITE这里继续进行send操作，同时要记住之前发送了多少。
