[edit]

staticconst locale& classic();

Obtains a reference to the C++ locale that implements the classic"C" locale semantics. This locale, unlike the global locale, cannot be altered.

[edit]Parameters

none

[edit]Return value

Returns a reference to the"C" locale.

[edit]Notes

Some of the standard-required facets, such as the UTF-8/UTF-32 conversion facetstd::codecvt<char32_t,char,std::mbstate_t>, have no equivalents in the"C" locale, but they are nevertheless present in the locale returned bystd::locale::classic(), as in any other locale constructed in a C++ program.
