Unnamed/anonymous namespaces vs. static functions

Question

A feature of C++ is the ability to create unnamed (anonymous) namespaces, like so:

namespace {
    int cannotAccessOutsideThisFile() { ... }
} // namespace
<         


        

Answer 1

In addition if one uses static keyword on a variable like this example:

namespace {
   static int flag;
}

It would not be seen in the mapping file
