Class Description

                                                                      
 TFTP                                                                 
                                                                      
 This class provides all infrastructure for a performant file         
 transfer protocol. It works in conjuction with the rootd daemon      
 and can use parallel sockets to improve performance over fat pipes.  
                                                                      

 Open connection to host specified by the url using par parallel sockets.
 The url has the form: [root[s]://]host[:port].
 If port is not specified the default rootd port (1094) will be used.
 Using wsize one can specify the tcp window size. Normally this is not
 needed when using parallel sockets.

 Set up the actual connection.

 TFTP dtor. Send close message and close socket.

 Print some info about the FTP connection.

 Print error string depending on error code.

 Return status from rootd server and message kind. Returns -1 in
 case of error otherwise 8 (sizeof 2 words, status and kind).

 Make sure the block size is a power of two, with a minimum of 32768.

 Transfer file to remote host. Returns number of bytes
 sent or < 0 in case of error. Error -1 connection is still
 open, error -2 connection has been closed. In case of failure
 fRestartAt is set to the number of bytes correclty transfered.
 Calling PutFile() immediately afterwards will restart at fRestartAt.
 If this is not desired call SetRestartAt(0) before calling PutFile().
 If rootd reports that the file is locked, and you are sure this is not
 the case (e.g. due to a crash), you can force unlock it by prepending
 the remoteName with a '-'.

 Transfer file from remote host. Returns number of bytes
 received or < 0 in case of error. Error -1 connection is still
 open, error -2 connection has been closed. In case of failure
 fRestartAt is set to the number of bytes correclty transfered.
 Calling GetFile() immediately afterwards will restart at fRestartAt.
 If this is not desired call SetRestartAt(0) before calling GetFile().
 If rootd reports that the file is locked, and you are sure this is not
 the case (e.g. due to a crash), you can force unlock it by prepending
 the file name with a '-'.

 Change the remote directory. If the remote directory contains a .message
 file and it is < 1024 characters then the contents is echoed back.
 Returns 0 in case of success and -1 in case of failure.

 Make a remote directory. Anonymous users may not create directories.
 Returns 0 in case of success and -1 in case of failure.

 Delete a remote directory. Anonymous users may not delete directories.
 Returns 0 in case of success and -1 in case of failure.

 List remote directory. With cmd you specify the options and directory
 to be listed to ls. Returns 0 in case of success and -1 in case of
 failure.

 Print path of remote working directory. Returns 0 in case of succes and
 -1 in cse of failure.

 Rename a remote file. Anonymous users may not rename files.
 Returns 0 in case of success and -1 in case of failure.

 Delete a remote file. Anonymous users may not delete files.
 Returns 0 in case of success and -1 in case of failure.

 Change permissions of a remote file. Anonymous users may not
 chnage permissions. Returns 0 in case of success and -1 in case
 of failure.

 Close ftp connection. Returns 0 in case of success and -1 in case of
 failure.
