NAME

       MPI_File_iwrite_at -  Nonblocking write using explicit offset

SYNOPSIS

       #ifdef HAVE_MPI_GREQUEST
       #include "mpiu_greq.h"
       #endif

       int MPI_File_iwrite_at(MPI_File fh, MPI_Offset offset, ROMIO_CONST 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.   ierr  is
       an  integer and has the same meaning as the return value of 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 ) are of type INTEGER in
       Fortran.
