Depends. Are we talking a COM supporting one? There are three flavors of 
dll, one has internal entry points that you need a linking table to get 
at. I.e., there is no stored internal data on what is there. Full COM 
supporting ones (one ones using any such variation on the concept) 
include an internal table and some standard method of "asking" what all 
the calls, variables, types, etc. are. The third is a kind of hybred, 
where "some" of the internals are exposed via the interface, but others 
have been intentionally designed to only allow linking using the 
header/table used to inform a compiler what they are.
