Re: DLM returning a pointer...

[Richard Younger <younger(at)ll.mit.edu>]

PS- 
The object is another layer of abstraction, but it needn't be difficult.
IDL code might look something like this, ignoring argument checking,
error checking, etc.  You can do that either on this level or on the
level of the C wrapper routines.


;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; File: DBinterface__define.pro

FUNCTION DBinterface::init

	self.struct_ptr = DBconnect_wrap
	RETURN, 1

END ;init

;-----------
PRO DBinterface::cleanup

	error = DBclose_wrap(self.struct_ptr)
	self.struct_ptr = 0ULL

END ;cleanup

;-----------
FUNCTION DBinterface::DBexecute, query	

	RETURN, DBexec_wrap(self.struct_ptr, query)
	
END

;-----------
FUNCTION DBinterface::DBgetval, index

	RETURN, DBgetv_wrap(self.struct_ptr, index)

END

;-----------
PRO DBinterface__define

	void = { $
		struct_ptr	:	0ULL		$
		}	

END ;DBinterface__define
