Declaring static function returning pointer to extern function
 

I want to declare a function that has static linkage and returns a
pointer to a function with extern linkage. Do the following
declarations acheive that, or do they declare a function that returns
a pointer to a function with static linkage?

typedef void Foo(void);
static Foo * Bar(void){
//Bar

}

There's no such thing as a distinction, in terms of type, between
pointers to functions base upon whether the pointed-at function has
internal linkage or external linkage. Linkage applies only to specific
function or object identifiers. That declaration makes Bar itself a
function with internal linkage, but allows it to return a pointer that
could equally easily point to a function with internal or external linkage.
