NAME
       MPI_File_iread -  Nonblocking read using individual file pointer

SYNOPSIS
       #include "mpi.h"
       int MPI_File_iread(MPI_File fh, void *buf, int count,
			  MPI_Datatype datatype, MPIO_Request *request)

INPUT PARAMETERS
       fh     - file handle (handle)
       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.
       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', 'MPI_File') are of type 'INTEGER' in Fortran.
