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)

           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.
