std::locale::name(3)

NAME
std::locale::name - std::locale::name

Synopsis
   Defined in header <locale>
   std::string name() const;
   Returns the name of the locale, which is the name by which it is known to the
   operating system, such as "POSIX" or "en_US.UTF8" or "English_United States.1252".
   If the locale is not a copy of a system-supplied locale, the string "*" is returned.

Return value
   The name of the locale or "*" if unnamed.

Example
// Run this code
 #include <iostream>
 #include <locale>
 #include <string>
 int main()
 {
     std::locale loc(std::locale(), new std::ctype<char>);
     std::cout << "The default locale is " << std::locale().name() << '\n'
               << "The user's locale is " << std::locale("").name() << '\n'
               << "A nameless locale is " << loc.name() << '\n';
 }

Possible output:
 The default locale is C
 The user's locale is en_US.UTF8
 A nameless locale is *
