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.

       MPI_File_open(3), MPI_IO(3)
