[Frama-c-discuss] From function definition to function declaration and back

I'm not too sure of what you want. Do you need access to the 
corresponding GVarDecl (that may not exist), in which case nothing is 
done (but a small visitor applied to the current AST should do the 
trick), or to the underlying kernel_function, in which case 
Globals.Function.get is exactly what you need (and then you have access 
to the functions of Kernel_function to retrieve more specific information).

Unfortunately, Cil_types.fundec is the type for function definitions. 
This does not really clarify the situation.
