示例1: transferDetachmentConn
// transferDetachmentConn transfers as much of a detachment as possible on a
// single connection. It calls sendStatus repeatedly with the current state of
// the transfer and watches killChan for an abort signal. It returns an error
// and an indication of whether the error is fatal. If not fatatl then another
// connection can be attempted in order to resume the transfer.

defer conn.Close()
// transferred is the number of bytes that *this connection* has transferred.
// total is the full length of the file.
