codecvt_base

class codecvt_base {
public:
    enum result {ok, partial, error, noconv};
    };

The class describes an enumeration common to all specializations of template class codecvt. The enumeration result describes the possible return values from do_in or do_out:

• error if the source sequence is ill-formed
• noconv if the function performs no conversion
• ok if the conversion succeeds
• partial if the destination is not large enough for the conversion to succeed
