* Pass mbrtowc() and wcrtomb() NULL instead of a pointer to a freshly zeroedTim J. Robbins2003-11-043-9/+3
| | | | | | | | | | 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.

* Rework the floating point code in printf(). Significant changes:David Schultz2003-04-052-151/+191
| | | | | | | | | | | | | | | | | | | | | - We used to round long double arguments to double. Now we print them properly. - Bugs involving '%F', corner cases of '#' and 'g' format specifiers, and the '.*' precision specifier have been fixed. - Added support for the "'" specifier to print thousands' grouping characters in a locale-dependent manner. - Implement the __vfprintf() side of hexadecimal floating point support. All that is still needed is a routine to convert the mantissa to hex digits one nibble at a time in the style of ultoa(). Reviewed by: silence on standards@ Notes: svn path=/head/; revision=113146

* Correct some buffer sizes.David Schultz2003-04-053-23/+42
| | | | | | | | | | | | | - __vfprintf()'s 'buf' has never been used for floating point, so don't define it in terms of (incorrect) constants describing floating point numbers. The actual size needed depends on sizeof(uintmax_t) and locale details, so I slightly overestimated. - We don't need a 308-character buffer to store the string "308". With long doubles and %a we need more than three characters, though. Notes: svn path=/head/; revision=113142

| | | | | | | | | | | | | | | | | | | | | package, a more recent, generalized set of routines. Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.
