Defined in header <locale>
class codecvt_base;

The class std::codecvt_base provides the conversion status constants which are inherited and used by the std::codecvt facets.

Member types

Member type	Definition
enum result { ok, partial, error, noconv };	Unscoped enumeration type

Enumeration constant	Definition
ok	conversion was completed with no error
partial	not all source characters were converted
error	encountered an invalid character
noconv	no conversion required, input and output types are the same

Notes

The value std::codecvt_base::partial is used to indicate that either the destination range is too short to receive the results of the conversion or the input is truncated in the middle of an otherwise valid multibyte character.
