Most of them are private.  You're only handed a "handle" (a pointer) to 
the internal data structures.  Pasteboard, Keyboard and Virtual Display
IDs are just pointers to structures that SMG$ has allocated, populated
and returned that pointer to you.  I have read from and I have modified
some of these internal structures (yeah, yeah, I know...) and even these
have not changed from VAX to Alpha to Itanium.

Save for the SMG$*_MENU requirement for an array of strings descriptor,
what is tricky about the "public" SMG$ structures?  FYI, Fortran would
create the descriptor necessary for SMG$*_MENU quite nicely.  I believe
BASIC did too.  Have fun if you're whacking SMG$ menu stuff with C.
