Access to virtual function table?

Is there any way in C++ to get access to the virtual function table for
a particular class? I'm trying to hack up, without yaccing up a
preprocessor, a ``monitor'' object that behaves like one of Hoare's
monitors. The entry and exit primitives are well defined, so that if
I'm willing to throw portability to the winds, I could just replace the
virtual function entries with things that do:
this.entry();
<call the original virtual function with the same arguments that
my caller gave me>
this.exit();
and for any of the machines that I'm expecting to deal with, this hook
is easy enough to build. I find that marginally superior to having to
remember to put entry() and exit() primitives in every member function.
What I *really* want (dream on) is something analogous to the :BEFORE,
:AFTER, and :AROUND specifiers in the ``flavors'' package (Smalltalk
has these too, but I don't remember what they're called).
