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.
