Tim J. Robbins	f9ceea9bf1	Call __mbrtowc() and __wcrtomb() directly instead of taking detours ... through mbrtowc() and wcrtomb().	2004-07-20 08:27:27 +00:00
Tim J. Robbins	87275e436a	Associate a multibyte conversion state object with each stream. Reset it ... to the initial state when a stream is opened or seeked upon. Use the stream's conversion state object instead of a freshly-zeroed one in fgetwc(), fputwc() and ungetwc(). This is only a performance improvement for now, but it would also be required in order to support state-dependent encodings.	2004-05-22 15:19:41 +00:00
Tim J. Robbins	93996f6d58	Prepare to handle trivial state-dependent encodings. Full support for ... state-dependent encodings with locking shifts will come later if there is demand for it.	2004-04-07 09:55:05 +00:00
Tim J. Robbins	a27a4b3690	Pass mbrtowc() and wcrtomb() NULL instead of a pointer to a freshly zeroed ... mbstate_t object that they ignore. The zeroing is fairly expensive, and it will never be necessary in these functions; when we support state-dependent encodings, we will pass in a pointer to the file's mbstate_t object, and only zero it at the time the file gets opened.	2003-11-04 11:05:55 +00:00
Tim J. Robbins	6180233fd8	Set the error bit on the stream if an encoding error occurs. Improve ... handling of multibyte sequences representing null wide characters.	2002-10-16 12:09:43 +00:00
Tim J. Robbins	5f147b57ac	Add an unlocked version of ungetwc(), __ungetwc(), that __vfwscanf() ... will need to use.	2002-09-22 05:59:00 +00:00
Tim J. Robbins	9260341650	Lock and unlock the file once per call and use the unlocked version of ... ungetc() instead of having ungetc() recurse on the lock.	2002-09-20 13:23:26 +00:00
Tim J. Robbins	24990dfad0	Reimplement the functionality of fgetrune(), fputrune(), and fungetrune() ... here in terms of mbrtowc(), wcrtomb(), and the single-byte I/O functions. The rune I/O functions are about to become deprecated in favour of the ones provided by ISO C90 Amd. 1 and C99.	2002-09-18 05:58:11 +00:00
Tim J. Robbins	e74101e4ef	Basic support for wide character I/O: getwc(), fgetwc(), getwchar(), ... putwc(), fputwc(), putwchar(), ungetwc(), fwide().	2002-08-13 09:30:41 +00:00
