MPI_File_seek(3)

NAME
     MPI_File_seek - Updates the individual file pointer

SYNOPSIS
     C:

          #include "mpi.h"

          int MPI_File_seek(MPI_File fh, MPI_Offset offset, int whence)


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER fh, whence, ierror
          INTEGER(KIND=MPI_OFFSET_KIND) offset

          CALL MPI_FILE_SEEK(fh, offset, whence, ierror)


DESCRIPTION
     MPI_File_seek updates the individual file pointer according to whence,
     which has the following possible values:

     *   MPI_SEEK_SET: the pointer is set to offset.

     *   MPI_SEEK_CUR: the pointer is set to the current pointer position plus
         offset.

     *   MPI_SEEK_END: the pointer is set to the end of file plus offset.

     The offset can be negative, which allows seeking backwards. You must not
     seek to a negative position in the view.

     MPI_File_seek accepts the following arguments:

     fh        Specifies the file handle (handle)

     offset    Specifies the file offset (integer)

     whence    Specifies the update mode (state)

     ierror    Specifies the return code value for successful completion,
               which is in MPI_SUCCESS.  MPI_SUCCESS is defined in the mpif.h
               file.

   Notes for Fortran
     All MPI objects (for example, MPI_Datatype, MPI_Comm, MPI_File) are of
     type INTEGER.
