`class error_category;`		(seit C++11)

std::error_category dient als Basisklasse für spezifische Fehler Kategorie Typen wie std::system_category, std::iostream_category, etc. Jede bestimmten Kategorie-Klasse definiert die error_code - error_condition Mapping und hält die erklärenden Strings für alle error_conditions. Die Objekte der Fehlerklasse Klassen werden als Singletons per Referenz übergeben behandelt .

Original:

std::error_category serves as the base class for specific error category types, such as std::system_category, std::iostream_category, etc. Each specific category class defines the error_code - error_condition mapping and holds the explanatory strings for all error_conditions. The objects of error category classes are treated as singletons, passed by reference.
