Mbsrtowcs
mbsrtowcs is a C standard-library function that converts a restartable multibyte character string to a wide-character string.
Modern C
mbsrtowcs is a C standard library function that converts a restartable multibyte string to a wide-character string.
- How it is used
- Converts multibyte strings for character counting and wide-character string processing.
- How deep it goes
- Shows counting and allocation calls, including conversion-state copies and error checks, without implementing the library function itself.
- Examples
- Uses mbsrlen to count characters and mbsrdup to allocate and fill a wide-character string.
- What you can do after
- Apply it via the C standard library to count multibyte-string characters and populate an allocated wide-character string.
Modern C, Third Edition
mbsrtowcs is a C standard-library function that converts a multibyte string to a wide character string while maintaining conversion state.
- How it is used
- Converts multibyte strings into wide character strings for extended-character processing.
- How deep it goes
- Explains the interface, state handling, length-query idiom, allocation pattern, and invalid-source handling without detailing implementation internals.
- Examples
- Demonstrates zero-length counting through mbsrlen and allocated conversion through mbsrdup.
- What you can do after
- Build converted wide strings and determine their required length while preserving conversion state.
