MPI_File_iwrite(3)

NAME
     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.

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