NAME
       MPI_Register_datarep -  Register functions for user-defined data  representations

SYNOPSIS
       int MPI_Register_datarep(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 rep-
       resentation, used within the CPU.  There is one predefined data representation, 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.
