class TRFIOFile: public TFile

 Create a RFIO file object. A RFIO file is the same as a TFile
 except that it is being accessed via a rfiod server. The url
 argument must be of the form: rfio:/path/file.root (where file.root
 is a symlink of type /shift/aaa/bbb/ccc) or rfio:server:/path/file.root.
 If the file specified in the URL does not exist, is not accessable
 or can not be created the kZombie bit will be set in the TRFIOFile
 object. Use IsZombie() to see if the file is accessable.
 For a description of the option and other arguments see the TFile ctor.
 The preferred interface to this constructor is via TFile::Open().

 RFIO file dtor. Close and flush directory structure.

 Read a list of buffers given in pos[] and len[] and return it
 in a single buffer. Returns kTRUE in case of error.

 Interface to system open. All arguments like in POSIX open.

 Interface to system close. All arguments like in POSIX close.

 Interface to system read. All arguments like in POSIX read.

 Interface to system write. All arguments like in POSIX write.

 Interface to system lseek. All arguments like in POSIX lseek
 except that the offset and return value are Long_t to be able to
 handle 64 bit file systems.

 Interface to TSystem:GetPathInfo(). Generally implemented via
 stat() or fstat().

 Method returning rfio_errno. For RFIO files must use this
 function since we need to check rfio_errno then serrno and finally errno.

 Method resetting the rfio_errno, serrno and errno.
