NAME
       MPI_File_iwrite_at -  Nonblocking write using explict offset

SYNOPSIS
       #include "mpi.h"
       int MPI_File_iwrite_at(MPI_File fh, MPI_Offset offset, void *buf,
			      int count, MPI_Datatype datatype,
			      MPIO_Request *request)

INPUT PARAMETERS
       fh     - file handle (handle)
       offset - file offset (nonnegative integer)
       buf    - initial address of buffer (choice)
       count  - number of elements in buffer (nonnegative integer)
       datatype
	      - datatype of each buffer element (handle)

OUTPUT PARAMETERS
       request
	      - request object (handle)

NOTES FOR FORTRAN
       All  MPI  routines  in Fortran (except for 'MPI_WTIME' and 'MPI_WTICK') have an additional argument 'ierr' at the end of the argument list.
       the routine in C.  In Fortran, MPI routines are subroutines and are invoked with the 'call' statement.

       All MPI objects (e.g., 'MPI_Datatype', 'MPI_Comm', 'MPI_File') are of type 'INTEGER' in Fortran.
