NAME

       MPI_File_get_byte_offset - Converts a view-relative offset into an absolute byte position.

SYNTAX

C Syntax

       #include    <mpi.h>   int   MPI_File_get_byte_offset(MPI_File   fh,   MPI_Offset   offset,
            MPI_Offset *disp)

Fortran Syntax (see FORTRAN 77 NOTES)

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_FILE_GET_BYTE_OFFSET(FH, OFFSET, DISP, IERROR)
            INTEGER   FH, IERROR
            INTEGER(KIND=MPI_OFFSET_KIND) OFFSET, DISP

C++ Syntax

       #include <mpi.h>
       MPI::Offset MPI::File::Get_byte_offset(const MPI::Offset disp)
            const

INPUT PARAMETERS

       fh        File handle (handle).

       offset    Offset (integer).

OUTPUT PARAMETERS

       disp      Absolute byte position of offset (integer).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

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

FORTRAN 77 NOTES

       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*MPI_OFFSET_KIND OFFSET
       or
            INTEGER*MPI_OFFSET_KIND DISP

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

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and
       Fortran routines in the last argument. C++ functions do not return errors. If the  default
       error  handler  is  set  to  MPI::ERRORS_THROW_EXCEPTIONS, 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 MPI_ERRORS_RETURN. The error handler
       may   be   changed   with   MPI_File_set_errhandler;   the   predefined   error    handler
       MPI_ERRORS_ARE_FATAL  may  be  used  to  make  I/O  errors  fatal.  Note that MPI does not
       guarantee that an MPI program can continue past an error.
