TRFIOFile
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
http://wwwinfo.cern.ch/pdp/serv/shift.html). TRFIOFile file names
are in standard URL format with protocol "rfio". The following are
valid TRFIOFile URL's:
rfio:/afs/cern.ch/user/r/rdm/galice.root
where galice.root is a symlink of the type /shift/.../...
rfio:na49db1:/data1/raw.root
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, Long_t *id, Long_t *size,
Long_t *flags, Long_t *modtime)
Get info about a file: id, size, flags, modification time.
Id is 0 for RFIO file
Size is the file size
Flags is file type: 0 is regular file, bit 0 set executable,
bit 1 set directory, bit 2 set special file
(socket, fifo, pipe, etc.)
Modtime is modification time.
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!!
