2020-03-20remove redundant condition in memccpyAlexander Monakov-1/+1
Commit d9bdfd164 ("fix memccpy to not access buffer past given size") correctly added a check for 'n' nonzero, but made the pre-existing test '*s==c' redundant: n!=0 implies *s==c. Remove the unnecessary check. Reported by Alexey Izbyshev.
2018-12-02fix memccpy to not access buffer past given sizeQuentin Rameau-1/+1
memccpy would return a pointer over the given size when c is not found in the source buffer and n reaches 0.
2018-09-26fix aliasing-based undefined behavior in string functionsRich Felker-3/+6
use the GNU C may_alias attribute if available, and fallback to naive byte-by-byte loops if __GNUC__ is not defined. this patch has been written to minimize changes so that history remains reviewable; it does not attempt to bring the affected code into a more consistent or elegant form.

2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker-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.
