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.
