MPI_Register_datarep(3)		      MPI	       MPI_Register_datarep(3)

NAME
       MPI_Register_datarep  -	Register functions for user-defined data  rep-
       resentations

SYNOPSIS
       int MPI_Register_datarep(MPICH2_CONST char *name,
			      MPI_Datarep_conversion_function *read_conv_fn,
			      MPI_Datarep_conversion_function *write_conv_fn,
			      MPI_Datarep_extent_function *extent_fn,
			      void *state)

INPUT PARAMETERS
       name   -	data representation name (string)
       read_conv_fn
	      -	function invoked to convert from file representation to	native
	      representation (function)
       write_conv_fn
	      -	function invoked to convert from native	representation to file
	      representation (function)
       extent_fn
	      -	function invoked to get	the exted of a datatype	as represented
	      in the file (function)
       extra_state
	      -	 pointer  to  extra  state that	is passed to each of the three
	      functions

NOTES
       This function allows the	user to	provide	routines to convert data  from
       an  external  representation, used within a file, and the native	repre-
       sentation, used within the CPU.	There is one predefined	data represen-
       tation,	external32 .  Please consult the MPI-2 standard	for details on
       this function.

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.
