std::locale

A locale object encompasses a set of features that are culture-specific, which can be used by programs to enhance international portability (see localization library for more info).

The localization engine, on construction of a locale object, initializes all the facets associated with it (if necessary) and makes them available to the program.

locale objects are generally constructed from a name (the same as the one that would be used with clocale function setlocale), or from another locale object. They can also mix facets from more than one locale object.

Every program has a single locale object which is its global locale. On start, this is the classic locale, but this can be changed using locale::global. This global locale is copied to any locale object constructed with its default constructor.

The global locale also affects the C locale (see clocale function setlocale): When a new named global locale is set with locale::global, the C locale is also modified.

locale objects can be used to access their associated facets in order to use their formatting features. They can also be imbued individually to specific stream objects (such as cin, cout or a file stream) by calling the stream's imbue member function.

See localization library for more information on locales and facets.
