MPI_File_iwrite(3)                    MPI                   MPI_File_iwrite(3)

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 mpi_fh, MPICH2_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.
