Yes. There is only one copy of the C function anyway. Putting the pragma
Interface/Import in a package, in a procedure, in a task, or in multiple
places does not change this and has _exactly_ the same effect, except
for the visibility of the function in your Ada code.

Yes, every instance of the task type gets its own copy, conceptually.
But the code of the local procedure will exist only once in the
object/executable file, and in memory, even if multiple calls are
simultaneously active.
