std::messages_byname
template <class charT> class messages_byname;
Facet to access message catalogs
The messages_byname standard facet overrides messages virtual members to implement its semantics for particular named locales.
Its public interface is the same as messages's, except that its constructor takes an additional std_name argument:
|
explicit messages_byname (const char* std_name, size_t refs = 0);
| |
1
2
|
explicit messages_byname (const char* std_name, size_t refs = 0);
explicit messages_byname (const string& std_name, size_t refs = 0);
| |
Where std_name is the name of a C locale. The C locales available depend on the system and library implementation, but at least the following are guaranteed to exist on all implementations:
| locale name | description |
|---|
"C" | Minimal "C" locale (the same as locale::classic) |
"" | The environment's default locale |
Specializations
At least the following specializations of this template are provided in all library implementations:
| specialization |
|---|
messages_byname<char> |
messages_byname<wchar_t> |
