[cfe-dev] [RFC] __attribute__((internal_linkage))

[Steven Stewart-Gallus via cfe-dev]

Hello,

Can I ask for some clarification?

Apparently, C++ doesn't allow to static class methods?

While in C one might write inside a header file:

static inline void mylib_foo_do_method(struct mylib_foo *foo) {
   // implementation here
}

In C++ the typical style would be to write something like:

namespace mylib {

void foo::do_method(void)
{
  // implementation here
}
}

Unfortunately, the C++ case then implies some linkage behaviour that
some might not want.

Apparently, one can't do things like:

namespace mylib {

static void foo::do_method(void)
{
  // implementation here
}
}

Or,

namespace {
namespace mylib {

static void foo::do_method(void)
{
  // implementation here
}
}
}

Also, if you wanted to an attribute to a whole namespace you should do
something like the following I think:

namespace mylib {
[[clang::internal_linkage]];

static void foo::do_method(void)
{
  // implementation here
}
}


Thank you,
