.. _mpi_file_get_byte_offset:
MPI_File_get_byte_offset
========================
.. include_body
:ref:`MPI_File_get_byte_offset` |mdash| Converts a view-relative offset into an
absolute byte position.
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_File_get_byte_offset(MPI_File fh, MPI_Offset offset,
MPI_Offset *disp)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: fortran
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
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: fortran
USE mpi_f08
MPI_File_get_byte_offset(fh, offset, disp, ierror)
TYPE(MPI_File), INTENT(IN) :: fh
INTEGER(KIND=MPI_OFFSET_KIND), INTENT(IN) :: offset
INTEGER(KIND=MPI_OFFSET_KIND), INTENT(OUT) :: disp
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
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
-----------
:ref:`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*.
ERRORS
