NAME

       MPI_File_iwrite -  Nonblocking write using individual file pointer

SYNOPSIS

       #ifdef HAVE_MPI_GREQUEST
       #include "mpiu_greq.h"
       #endif
       int MPI_File_iwrite(MPI_File fh, ROMIO_CONST void *buf, int count,
       MPI_Datatype datatype, MPI_Request * request)

INPUT PARAMETERS

       fh     - file handle (handle)
       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.
