The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
std::locale::id – std::locale::id Synopsis Defined in header <locale> class locale::id; The class std::locale::id provides implementation-specific identification of a locale facet. Each class derived from std::locale::facet must have a public static member named id of type std::locale::id and each std::locale object maintains a list of facets it implements, indexed by their ids. Facets with the same…
std::locale::global – std::locale::global Synopsis Defined in header<locale> static locale global(const locale &loc); Replaces the global C++ locale with loc, which means all future calls to the std::locale default constructor will now return a copy of loc.If loc has a name, also replaces the C locale as if by std::setlocale(LC_ALL, loc.name().c_str()); .This function is the only…
std::locale::facet::facet – std::locale::facet::facet Synopsis Defined in header<locale> explicit facet(std::size_t refs = 0); (1) facet(const facet &) = delete; (2) 1) creates a facet with starting reference count refs. If refs is non-zero, the facet will not be deleted when the last locale referencing it goes out of scope. A facet with static or dynamic storage…
std::locale::facet – std::locale::facet Synopsis Defined in header <locale> class locale::facet; std::locale::facet is the base class for facets. It provides a common base class so that locales could store pointers to the facets they implement in a single indexed container, and it abstracts support for facet reference counting. Whenever a facet is added to a locale,…

std::locale::classic – std::locale::classic Synopsis Defined in header<locale> static const 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. Parameters none Return value Returns a reference to the "C" locale. Notes Some of the standard-required facets, such as the UTF-8/UTF-32…
std::locale – std::locale Synopsis Defined in header <locale> class locale; An object of class std::locale is an immutable indexed set of immutable facets. Each stream object of the C++ input/output library is associated with an std::locale object and uses its facets for parsing and formatting of all data. In addition, a locale object is associated…
