Class Description

                                                                      
 TCastorFile                                                          
                                                                      
 A TCastorFile is like a normal TNetFile except that it obtains the   
 remote node (disk server) via the CASTOR API, once the disk server   
 and the local file path are determined, the file will be accessed    
 via the rootd daemon. File names have to be specified like:          
    castor:/castor/cern.ch/user/r/rdm/bla.root.                       
                                                                      
 If Castor 2.1 is used the file names can also be specified           
 in the following ways:                                               
                                                                      
  castor://stager_host:stager_port/?path=/castor/cern.ch/user/        
    r/rdm/bla.root&svcClass=MYSVCLASS&castorVersion=MYCASTORVERSION   
                                                                      
  castor://stager_host/?path=/castor/cern.ch/user/                    
    r/rdm/bla.root&svcClass=MYSVCLASS&castorVersion=MYCASTORVERSION   
                                                                      
  castor:///?path=/castor/cern.ch/user/                               
    r/rdm/bla.root&svcClass=MYSVCLASS&castorVersion=MYCASTORVERSION   
                                                                      
 path is mandatory as parameter but all the other ones are optional.
int ParseAndSetGlobal()
 This function does the parsing to deal with the new Turl
 and set the global variables needed by castor.
TCastorFile(const char *url, Option_t *option, const char *ftitle, Int_t compress, Int_t netopt)
 Create a TCastorFile. A TCastorFile is like a normal TNetFile except
 that it obtains the remote node (disk server) via the CASTOR API, once
 the disk server and the local file path are determined, the file will
 be accessed via the rootd daemon. File names have to be specified like:
    castor:/castor/cern.ch/user/r/rdm/bla.root.
 The other arguments are the same as for TNetFile and TFile.
void FindServerAndPath()
 Find the CASTOR disk server and internal file path.
Int_t SysClose(Int_t fd)
 Close currently open file.
Bool_t WriteBuffer(const char *buf, Int_t len)
 Write specified byte range to remote file via rootd daemon.
 Returns kTRUE in case of error.
void ConnectServer(Int_t *stat, EMessageTypes *kind, Int_t netopt, Int_t tcpwindowsize, Bool_t forceOpen, Bool_t forceRead)
 Connect to remote rootd server on CASTOR disk server.
TCastorFile(const char *url, Option_t *option = "", const char *ftitle = "", Int_t compress = 1, Int_t netopt = 0)
{ fIsCastor = fWrittenTo = kFALSE; }
virtual ~TCastorFile()
