const char* as a static member

[Alex Vinokur]

Is this library safe?

Does this have to do with Position Independent Code?

====== Library ======

--- File foo.h ---

struct Foo
{
static const char* s_name;
// Stuff
};

-------------------

--- File foo.cpp ---

const char* Foo::s_name = "ABCD";

// Stuff

-------------------

The posted code is perfectly safe according to the C++
standard.

Position Independent Code does not "exist" in C++.
As I understand it, PIC is an implementation detail of
generated code on some platforms, where only PC-relative
addresses are used to allow the code to be relocated
in memory without requiring any absolute address fixing.
I don't see that the above code illustrates anything
specifically related to PIC.
