I ahev written a win32 D DLL and exposed its functions so I can call it
from PG. However, I want to export the function names by ordinal, rather
than by name (for several reasons - one of which, is to reduce the size
of the DLL).

My question is:

Does any one know how I can call a function exported by ordinal number
(as opposed to name), from a DLL.

If this is possible, I will be very grateful for an example of
a CREATE FUNCTION statement which shows a function being called by
ordinal number rather than name.
