C/C++: `const` position in function's argument list

Question

void func1 (const int *);
void func2 (int const *);
void func3 (int * const);

Which two signatures are equivalent? If none of them are, can you please explain the subtle differences?

Thank you for the link to the other question! It offers an great way to remember how they work, "Read it backwards." — Zak, Oct 07 '13 at 16:13

The first two are equivalent (the int is const), in the third it's the pointer that's const (i.e. the parameter itself).
