class codecvt_base; | ||
The classstd::codecvt_base provides the conversion status constants which are inherited and used by thestd::codecvt facets.
| Member type | Definition |
| enum result{ ok, partial, error, noconv}; | Unscoped enumeration type |
| Value | Explanation |
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 |
The valuestd::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.
| converts between character encodings, including UTF-8, UTF-16, UTF-32 (class template)[edit] |
