The message facet constructor function.
explicit messages(
    size_t _Refs = 0
);
protected: messages(
    const char *_Locname,
    size_t _Refs = 0
);
Parameters
- _Refs 
 Integer value used to specify the type of memory management for the object.
- _Locname 
 The name of the locale.
Remarks
The possible values for the _Refs parameter and their significance are:
- 0: The lifetime of the object is managed by the locales that contain it. 
- 1: The lifetime of the object must be manually managed. 
- > 0: These values are not defined. 
No direct examples are possible, because the destructor is protected.
The constructor initializes its base object with locale::facet(_Refs).
