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.

Function documentation

TFTP(const char* url, Int_t parallel = 1, Int_t wsize = kDfltWindowSize, TSocket* sock = 0)
 Open connection to host specified by the url using par parallel sockets.
 The url has the form: [root[s,k]://]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.
 An existing connection (TSocket *sock) can also be used to establish
 the FTP session.
void Init(const char* url, Int_t parallel, Int_t wsize)
 Set up the actual connection.
~TFTP()
 TFTP dtor. Send close message and close socket.
void Print(Option_t* opt = "") const
 Print some info about the FTP connection.
void PrintError(const char* where, Int_t err) const
 Print error string depending on error code.
Int_t Recv(Int_t& status, EMessageTypes& kind) const
 Return status from rootd server and message kind. Returns -1 in
 case of error otherwise 8 (sizeof 2 words, status and kind).
void SetBlockSize(Int_t blockSize)
 Make sure the block size is a power of two, with a minimum of 32768.
Long64_t PutFile(const char* file, const char* remoteName = 0)
 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 '-'.
Long64_t GetFile(const char* file, const char* localName = 0)
 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 '-'.
Int_t ChangeDirectory(const char* dir) const
 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.
Int_t MakeDirectory(const char* dir, Bool_t print = kFALSE) const
 Make a remote directory. Anonymous users may not create directories.
 Returns 0 in case of success and -1 in case of failure.
Int_t DeleteDirectory(const char* dir) const
 Delete a remote directory. Anonymous users may not delete directories.
 Returns 0 in case of success and -1 in case of failure.
Int_t ListDirectory(Option_t* cmd = "") const
 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.
Int_t PrintDirectory()
 Print path of remote working directory. Returns 0 in case of succes and
 -1 in cse of failure.
Int_t RenameFile(const char* file1, const char* file2) const
 Rename a remote file. Anonymous users may not rename files.
 Returns 0 in case of success and -1 in case of failure.
Int_t DeleteFile(const char* file) const
 Delete a remote file. Anonymous users may not delete files.
 Returns 0 in case of success and -1 in case of failure.
Int_t ChangePermission(const char* file, Int_t mode) const
 Change permissions of a remote file. Anonymous users may not
 chnage permissions. Returns 0 in case of success and -1 in case
 of failure.
Int_t Close()
 Close ftp connection. Returns 0 in case of success and -1 in case of
 failure.
Bool_t OpenDirectory(const char* name, Bool_t print = kFALSE)
 Open a directory via rootd.
 Returns kTRUE in case of success.
 Returns kFALSE in case of error.
void FreeDirectory(Bool_t print = kFALSE)
 Free a remotely open directory via rootd.
const char * GetDirEntry(Bool_t print = kFALSE)
 Get directory entry via rootd.
 Returns 0 in case no more entries or in case of error.
Int_t GetPathInfo(const char* path, FileStat_t& buf, Bool_t print = kFALSE)
 Get info about a file. Info is returned in the form of a FileStat_t
 structure (see TSystem.h).
 The function returns 0 in case of success and 1 if the file could
 not be stat'ed.
Bool_t AccessPathName(const char* path, EAccessMode mode = kFileExists, Bool_t print = kFALSE)
 Returns kFALSE if one can access a file using the specified access mode.
 Mode is the same as for the Unix access(2) function.
 Attention, bizarre convention of return value!!
