MPI_File_iwrite_at_all(3)             MPI            MPI_File_iwrite_at_all(3)

NAME
       MPI_File_iwrite_at_all -  Nonblocking collective write using explicit
       offset

SYNOPSIS
       int MPI_File_iwrite_at_all(MPI_File fh, MPI_Offset offset, ROMIO_CONST void *buf,
                                  int count, MPI_Datatype datatype,
                                  MPI_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.
