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.
