       fh        File handle (handle).

       offset    Offset (integer).

       disp      Absolute byte position of offset (integer).

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPIFilegetbyteoffset converts an offset specified for  the  current
       view  to  its  corresponding displacement value, or absolute byte posi-
       tion, from the beginning of the file. The  absolute  byte  position  of
       offset relative to the current view of fh is returned in disp.


FFOORRTTRRAANN 7777 NNOOTTEESS
       The  MPI standard prescribes portable Fortran syntax for the OFFSET and
       DISP arguments only for Fortran 90. Sun FORTRAN 77 users  may  use  the
       non-portable syntax

            INTEGER*MPIOFFSETKIND OFFSET
       or
            INTEGER*MPIOFFSETKIND DISP

       where  MPIOFFSETKIND  is  a  constant defined in mpif.h and gives the
       length of the declared integer in bytes.


EERRRROORRSS
       Almost all MPI routines return an error value; C routines as the  value
       of  the  function  and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default  error  handler  is  set  to
       MPI::ERRORSTHROWEXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI  error  handler  is
       called.  For  MPI I/O function errors, the default error handler is set
       to  MPIERRORSRETURN.  The  error  handler   may   be   changed   with
       MPIFileseterrhandler;      the      predefined     error     handler
       MPIERRORSAREFATAL may be used to make I/O errors  fatal.  Note  that
       MPI  does not guarantee that an MPI program can continue past an error.
