What does this function definition mean?

Question

This function definition is found here. :

static void (*resolve_memcpy (void)) (void)
{
    return my_memcpy; // we'll just always select this routine
}

I don't understand what it means.

resolve_memcpy is a function taking no arguments and returning a pointer to a function taking no arguments and returning void.
