MPI_File_iwrite - Nonblocking write using individual file
       pointer


SYNOPSIS

       C:

            #include "mpi.h"

            int MPI_File_iwrite (MPI_File fh, void *buf,
            int count, MPI_Datatype datatype, MPIO_Request *request)

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            <type> BUF(*)
            INTEGER fh, count, datatype, request, ierror

            CALL MPI_FILE_IWRITE(fh, buf, count, datatype,
            request, ierror)


DESCRIPTION

       MPI_File_iwrite is a nonblocking version of the
       MPI_FILE_WRITE interface.

       MPI_File_iwrite accepts the following arguments:

       fh        Specifies the file handle (handle)

       buf       Specifies the initial address of the buffer
                 (choice)

       count     Specifies the number of elements in the buffer
                 (nonnegative integer)

       datatype  Specifies the datatype of each buffer element
                 (handle)

       request   Returns the request object (handle)

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
                 MPI_SUCCESS is defined in the mpif.h file.

   Limitations
       In Fortran and C, the routines MPIO_Wait and MPIO_Test
       must be used instead of MPI_Wait and MPI_Test,
       respectively.  This is a nonstandard restriction and might
       change in an upcoming release.

       All MPI objects (for example, MPI_Datatype, MPI_Comm,
       MPI_File) are of type INTEGER.
