2002-11-27Fix an ifdef mismatch.Manuel Novoa III
2002-11-22Ok... here's the summary:Manuel Novoa III
Hopefully locale support will build when cross compiling now. Collation is still not supported, but that's what I'm currently working on. In the next couple of days, I'll probably put up a couple of files for download that will save people the trouble of generating all the glibc locales. Added *wprintf functions, although they currently don't support floating point. That will be fixed when I rewrite _dtostr... or possibly before. Added the wcsto{inttype} functions. Added iconv() and a mini iconv utility. The require locale support and only provide for conversions involving the various unicode encodings { UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built with the locale data, and the internal WCHAR_T.
2002-11-04Add printf wchar support for %lc (%C) and %ls (%S).Manuel Novoa III
Require printf format strings to be valid multibyte strings beginning and ending in their initial shift state, as per the stds. Fixed a bug in _wchar_wcsntoutf8s(). Don't store wcs position if dst is NULL. Also, introduce an awful hack into _wchar_wcsntoutf8s() and wcsrtombs() in order to support %ls in printf. See comments below for details. Change behaviour of wc<->mb functions when in the C locale. Now they do a 1-1 map for the range 0x80-UCHAR_MAX. This is for backwards compatibility and consistency with the stds requirements that a printf format string by a valid multibyte string beginning and ending in it's initial shift state.
2002-11-03It was easy enough to respect locale-specific decimal point for printfManuel Novoa III
floating point output, so at least implement that. But grouping will have to wait for the rewrite of _dtostr.
2002-11-03Implement locale-specific grouping in printf for base 10 integer conversionsManuel Novoa III
when the grouping flag "'" is specified. Grouping for floating point values may wait until I do a rewrite of the floating pt to string code...

2002-10-29Fix a problem in vasprintf (reported by vodz a while back) when builtManuel Novoa III
without custom stream support. In that case, it is necessary to do a va_copy. Note: The affected code is not built in the stock config. Also, make sure each va_copy has a matching va_end, as required by C99.
2002-08-17Fix two problems with printf that showed up in the python 2.2.1 tests;Manuel Novoa III
One involving %o and one involving %f.
2002-08-13__fsetlocking() and FILE field user_locking were completely broken. :-(Manuel Novoa III
I think they're fixed now (I've run a few tests). Note: __fsetlocking() is not threadsafe... but glibc's doesn't appear to be either.
2002-08-12Revert commit by davidm to printf.c that initialized conv_numManuel Novoa III
needlessly. To do so increases the generated code size with bcc. Eliminate duplicate define warnings in wstring.c. Fix potentially broken preprocessor comparisons. The preprocessor converts integers to maximal signed type, so inequality comparisons involving UINTMAX_MAX, ULLONG_MAX, and (if no long long) ULONG_MAX were potentially broken.
2002-08-09Fix a number of compile time warnings so that uClibc will build with -Werror ↵David McCullough
using a 3.0.4 version of the sh-linux-gcc compiler.
2002-07-07Attempt to clean up the strerror_r situation.Manuel Novoa III
2002-07-03Enable WCHAR support for C/POSIX stub locales.Manuel Novoa III
Implemented unformatted wide i/o functions. (ungetwc still needs testing) Fix a few bugs in wchar.c. Modifications for bcc/elks support.
2002-06-18Fix perror() and printf("%m") to not call strerror(), as required by theManuel Novoa III
standards. Temporarily added a utility function to wrap Erik's strerror_r so that "Unknown error xxx" strings can be generated for errno's which cause strerror_r to fail. That utility function will eventually be merged in with the strerror/strerror_r functions when I change over to optionallly mmap'ing the system error strings to provide for lower mem comsumption on non-MMU platforms, as well as locale-specific system error messages.
2002-06-11Revert Erik's patch to vasprintf and fix the real issue.Manuel Novoa III
The writer for the stream returned by open_memstream was supposed to keep the buffer nul-terminated. I apparently left out a statement.
2002-06-11This patch from Rik Faith <faith@alephnull.com> fixes a potentiallyEric Andersen
non-NULL terminated string problem that could result from the use of open_memstream(). Manuel may have a better solution, but this one works for me, since with this plus the popen fix I can now run things like gdb properly. Thanks Rik!
2002-05-12Several bugfixes for problems that showed up on alphaEric Andersen

2002-05-11Adjust preprocessor logic to initialize QUAL_CHARS correctly for Erik's alphaManuel Novoa III
port. Also, explicitly use the macro versions of isdigit and isspace in the printf and scanf code.

2002-03-12Fix another O_LARGEFILE bug. Also, I forget to make floating point optionalManuel Novoa III

2001-06-13Fix printf so that %p outputs "(nil)" for (void *) 0, to match glibc behavior.Manuel Novoa III
2001-06-13Fix printf handling of %p to prepend "0x" since output is in hex.Manuel Novoa III
Note: glibc output for (void *)0 is "(nil)" while uClibc output is "0". Does anyone have a preference?

2001-02-27stdio mostly rewritten... passes lots of tests now.Manuel Novoa III
printf now supports long double, plus some bug fixes.
2001-02-19Lots of stdio cleanups. Several bug fixes, addition of a number of functionsManuel Novoa III
to supplement macros in stdio.h, change perror to use stdio package instead of "write". Also add back in weak stdio initialization for static lib case.
2001-02-15Add vdprintf function. Note: will be rewritten to check if file descriptor ↵Manuel Novoa III
has an associated FILE to avoid bad interactions with buffered output, but needed for busybox right now and that implementation has the same bug.
2001-01-30Fix a couple of bugs in printf. Add floating pt output for doubles. Yeah!Manuel Novoa III
Modified stdio/Makefile to build printf.c according to Config values for HAS_FLOATS and HAS_LONG_LONG.
2001-01-28Really fixed 0-pad bug this time. ;-) Code-size reductions if sizeof(int) andManuel Novoa III
sizeof(long) equal. printf # flag now works for b (binary) specifier.
2001-01-27Fixed (hopefully) 0-pad bug in printf. Added asprintf function. ReworkedManuel Novoa III
the *s*printf functions to no longer use a static fake file.
