    func (c *Connection) NotifyClose(receiver chan *Error) chan *Error<\/p>\n

    NotifyClose registers a listener for close events either initiated by an error accompanying a connection.close method or by a normal shutdown.<\/p>\n

    On normal shutdowns, the chan will be closed.<\/p>\n

    To reconnect after a transport or protocol error, register a listener here and re-run your setup process. <\/p><\/div>\n<\/p><\/div>\n<\/li>\n
