* Fix some style bugsAlexey Zelkin2001-12-171-15/+18
| | | | | | | Prompted by: mike Notes: svn path=/head/; revision=88057
* Also fix cases when thousands separator should be put before number. ForAlexey Zelkin2001-12-131-2/+4
| | | | | | | | example before for grouping sequence "\003\003" number 123456 was formated as ",123,456", now "123,456". Notes: svn path=/head/; revision=87818
* Respect locale while handling of \' flag.Alexey Zelkin2001-12-131-22/+63
| | | | | | | | | | | | | In original version grouping was hardcoded. It assumed that thousands separator should be inserted to separate each 3 numbers. I.e. grouping string "\003" was assumed for all cases. In correct case (per POSIX) vfprintf should respect locale defined non-monetary (LC_NUMERIC category) grouping sequence. Also simplify thousands_sep handling. Notes: svn path=/head/; revision=87815

* * localeconv() usage is not FLOATING_POINT specific anymore (due to "'" flagAlexey Zelkin2001-12-071-3/+3
| | | | | | | | addition) so move locale.h inclusion out of FLOATING_POINT ifdef's. * add more comments Notes: svn path=/head/; revision=87490

* Implement several of the c99 updates to printf(3):Bill Fenner2001-11-302-211/+458
| | | | | | | | | | | | | | | | | | | - New length modifiers: hh, j, t, z. - New flag: '. Note that %'f is not yet implemented. - Use "inf"/"nan" for efg formats, "INF"/"NAN" for EFG formats. - Implemented %q in terms of %ll; if "quad_t" is not "long long" %q will break. Still to do: - %C, %S, %lc, %ls (wide character support) - %'f (thousands in integer portion of %f) - %a/%A (exact hex representation of floating-point numbers) Garrett Wollman wrote the first version of the vfprintf.c update; Mike Barcroft wrote the first version of the printf.3 changes. Notes: svn path=/head/; revision=87113
* Back out national digits support, POSIX explicetely disallows it:Andrey A. Chernov2001-11-291-53/+55
| | | | | | | | | | | | | | The definition of character class digit requires that only ten characters -the ones defining digits- can be specified; alternate digits (for example, Hindi or Kanji) cannot be specified here. However, the encoding may vary if an implementation supports more than one encoding. The definition of character class xdigit requires that the characters included in character class digit are included here also and allows for different symbols for the hexadecimal digits 10 through 15.

| | | | | | | | our pre-check control. Do the same way as refill.c does when it set __SERR, i.e. clear read and ungetc buffers. Clear EOF flag too. Notes: svn path=/head/; revision=85418
* Back out read buffer invalidating via __SMOD.Andrey A. Chernov2001-10-232-7/+2
| | | | | | | | It was correct, but not needed because internal buffer cleared on each seek outside of it. Notes: svn path=/head/; revision=85396

* 1) If __SAPP stream is not seekable, remove __SAPP flag on first call insteadAndrey A. Chernov2001-09-071-3/+10
| | | | | | | | | | | | of repeating unsuccessful lseek call on each write (original stdio bug). 2) Save errno accross _sseek call in _swrite to not touch it in case write success (original stdio bug). 3) Add _sseek error checking back, but only for __SOPT mode now. Notes: svn path=/head/; revision=83211
* For now just back out seek error checking in __SAPP case, it cause problemsAndrey A. Chernov2001-09-071-2/+2
| | | | | | | | | with non-seekable streams. Now here is what here was originally, but it is ugly, producing unneded seek syscall on each non-seekable stream write. I'll think about proper solution later. Notes: svn path=/head/; revision=83177
* When __SOPT is cleared, clear __SOFF too.Andrey A. Chernov2001-09-031-1/+1
| | | | | | | NOTE: original stdio bug. Notes: svn path=/head/; revision=82839

* Internal seeks are overoptimized. They should remember fp->_offset only forAndrey A. Chernov2001-09-022-3/+1
| | | | | | | | | | plain regular files, i.e. files with __SOPT flag set. Fix it, so ftell(stdout) always returns the same as lseek(1, 0, 1) now. NOTE: this bug was in original stdio code Notes: svn path=/head/; revision=82827
* Fix bug in off_t overflow checking: if fp->_offset overflows, just removeAndrey A. Chernov2001-09-021-5/+3
| | | | | | | | __SOFF flag (i.e. we don't have offset) instead of returning EOVERFLOW. It allows again continious reading from non-stop stream. Notes: svn path=/head/; revision=82818
* Typo seek(2) -> lseek(2)Andrey A. Chernov2001-09-021-1/+1

* Move all stdio internal flags processing and setting out of __sread(),Andrey A. Chernov2001-09-029-55/+89
| | | | | | | | | | | | | __swrite() and __sseek() to higher level. According to funopen(3) they all are just wrappers to something like standard read(2), write(2) and lseek(2), i.e. must not touch stdio internals because they are replaceable with any other functions knows nothing about stdio internals. See example of funopen(3) usage in sendmail sources f.e. NOTE: this is original stdio bug, not result of my range checkin added. Notes: svn path=/head/; revision=82807
* Save errno before function call and restore it on success (because manyAndrey A. Chernov2001-09-012-2/+11
| | | | | | | | | internal functions there may fail and set (i.e. overwrite) errno in normal (not error) situation). In original variant errno testing after call (as POSIX suggest) is wrong when errno overwrite happens. Notes: svn path=/head/; revision=82743
