How does it happen that in header it's `const void*` but in cpp file it's `void
const* p`?

Not using copy-paste, in all likelihood. I really don't recall; I wrote this
code months ago.

+{
+  std::wstringstream ss;
+  ss << L"0x";
+  ss.width(sizeof(p) * 2);
+  ss.fill(L'0');
+  ss << std::hex << reinterpret_cast<voidIntegral>(p);
+  return ss.str();
+}
