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
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Cheers,
Rich
