Class Description

 A TRFIOFile is like a normal TFile except that it reads and writes   
 its data via a rfiod server (for more on the rfiod daemon see TRFIOFile file names    
 are in standard URL format with protocol "rfio". The following are   
 valid TRFIOFile URL's:                                               
         where galice.root is a symlink of the type /shift/.../...    

TRFIOSystem() : TSystem("-rfio", "RFIO Helper System")
 Create helper class that allows directory access via rfiod.

Int_t MakeDirectory(const char *dir)
 Make a directory via rfiod.

void* OpenDirectory(const char *dir)
 Open a directory via rfiod. Returns an opaque pointer to a dir
 structure. Returns 0 in case of error.

void FreeDirectory(void *dirp)
 Free directory via rfiod.

const char* GetDirEntry(void *dirp)
 Get directory entry via rfiod. Returns 0 in case no more entries.

Int_t GetPathInfo(const char *path, FileStat_t &buf)
 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)
 Returns FALSE 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!!
