MPI_File_iread_at(3)		      MPI		  MPI_File_iread_at(3)

NAME
       MPI_File_iread_at -  Nonblocking	read using explicit offset

SYNOPSIS
       int MPI_File_iread_at(MPI_File fh, MPI_Offset offset, void *buf,	int count, MPI_Datatype	datatype,
       MPIO_Request * request)

INPUT PARAMETERS
       fh     -	file handle (handle)
       offset -	file offset (nonnegative integer)
       count  -	number of elements in buffer (nonnegative integer)
       datatype
	      -	datatype of each buffer	element	(handle)

OUTPUT PARAMETERS
       buf    -	initial	address	of buffer (choice)
       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.
