2019-03-12	setvbuf: return failure if mode is invalid	A. Wilcox	1	-1/+3
	POSIX requires setvbuf to return non-zero if `mode` is not one of _IONBF, _IOLBF, or _IOFBF.
2018-07-13	fix writes outside buffer by ungetc after setvbuf	Rich Felker	1	-1/+1
	commit 0b80a7b0404b6e49b0b724e3e3fe0ed5af3b08ef, which added non-stub setvbuf, applied the UNGET pushback adjustment to the size of the buffer passed in, but inadvertently omitted offsetting the start by the same amount, thereby allowing unget to clobber up to 8 bytes before the start of the buffer. this bug was introduced in the present release cycle; no releases are affected.
2018-04-19	setvbuf: minor comment typo fix	Will Dietz	1	-1/+1

2018-04-18	add support for caller-provided buffers to setvbuf	Rich Felker	1	-11/+14

2012-09-06	use restrict everywhere it's required by c99 and/or posix 2008	Rich Felker	1	-1/+1
	to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
2011-03-28	major stdio overhaul, using readv/writev, plus other changes	Rich Felker	1	-1/+3
	the biggest change in this commit is that stdio now uses readv to fill the caller's buffer and the FILE buffer with a single syscall, and likewise writev to flush the FILE buffer and write out the caller's buffer in a single syscall. making this change required fundamental architectural changes to stdio, so i also made a number of other improvements in the process: - the implementation no longer assumes that further io will fail following errors, and no longer blocks io when the error flag is set (though the latter could easily be changed back if desired) - unbuffered mode is no longer implemented as a one-byte buffer. as a consequence, scanf unreading has to use ungetc, to the unget buffer has been enlarged to hold at least 2 wide characters. - the FILE structure has been rearranged to maintain the locations of the fields that might be used in glibc getc/putc type macros, while shrinking the structure to save some space. - error cases for fflush, fseek, etc. should be more correct. - library-internal macros are used for getc_unlocked and putc_unlocked now, eliminating some ugly code duplication. __uflow and __overflow are no longer used anywhere but these macros. switch to read or write mode is also separated so the code can be better shared, e.g. with ungetc. - lots of other small things.
