Mbstate_t
mbstate_t is a C standard-library type representing the conversion state required by restartable multibyte-character functions.
Modern C, Third Edition
mbstate_t is the C standard-library type that represents the conversion state required by restartable multibyte character functions.
- How it is used
- Tracks conversion progress while multibyte text is parsed across calls or input-buffer boundaries.
- How deep it goes
- Works through persistent, copied, and backed-up state in conversion code; does not describe the representation inside `mbstate_t`.
- Examples
- Uses `mbsrlen` and `mbsrwc` helpers plus a fixed-buffer `mbrtoc8` input scanner.
- What you can do after
- Build it from scratch: preserve and pass conversion state when scanning multibyte input that may end mid-character.
Modern C
mbstate_t is a C library type that stores the conversion state needed to interpret multibyte character sequences.
- How it is used
- Tracks the context needed to parse multibyte characters while scanning strings.
- How deep it goes
- Defines the type’s role and shows state copied and passed to conversion functions, without detailing its representation.
- Examples
- Uses mbsrlen to count characters and mbsrwc to retain the state at a search match.
- What you can do after
- Build it from scratch in multibyte string helpers that pass or copy a consistent conversion state.
