* Perform conversions straight from the stream buffer instead of scanningTim J. Robbins2004-05-221-18/+19
| | | | | | | | | | through byte by byte with mbrtowc(). In the usual case (buffer is big enough to contain the multibyte character, character does not straddle buffer boundary) this results in only one call to mbrtowc() for each wide character read. Notes: svn path=/head/; revision=129584
* Associate a multibyte conversion state object with each stream. Reset itTim J. Robbins2004-05-227-42/+24
| | | | | | | | | | | | 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. Notes: svn path=/head/; revision=129583

| | | | | | | | | | | | floating-point support, remove default definition of FLOATING_POINT from the source, and change the compile-time option to NO_FLOATING_POINT. - Remove the HEXFLOAT option. It saves an insignificant amount of space (<0.1% of the size of libc on i386) and complicates vfprintf() and checkfmt(). Notes: svn path=/head/; revision=128819

This change makes most (relevant) stdio functions work again when the _extra file in FILE isn't initialised (and can't be without a libc function to do it since the __sFILEX structure is private to libc).

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.
