DLLSYM void* de_serialise_bytes	(	FILE *	f,
		int	size
	)

read non-class items, bytes

These are the only routines that write/read data to/from the serialisation.

"serialise_bytes" and "de_serialise_bytes" are used to serialise NON class items. The "make_serialise" macro generates "serialise" and "de_serialise" member functions for the class name specified in the macro parameter.
