Defined in header <system_error>
const std::error_category& generic_category();
(seit C++11)
Ruft einen Verweis auf den statischen Fehler Kategorie-Objekt für generische Fehler. Das Objekt ist erforderlich, um die virtuelle Funktion error_category::name() überschreiben, um einen Zeiger auf den String "generic" zurückzukehren. Es wird verwendet, um Fehlerbedingungen, die zu den POSIX errno-Codes entsprechen, zu identifizieren .
Original:
Obtains a reference to the static error category object for generic errors. The object is required to override the virtual function error_category::name() to return a pointer to the string "generic". It is used to identify error conditions that correspond to the POSIX errno codes.
