What you choose not to notice is the context in which I asked these  
The context is: Haskell functions as first-class objects.
What I am interested in the first place is dynamically linked libraries  
written in Haskell and used in Haskell.
The interface with other languages like C come second.

What is the definition of an entry point in Haskell ?
What is the semantics of those entry points ?
