remove redundant condition in memccpy

2020年03月20日T19:45:08+00:00

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.

fix memccpy to not access buffer past given size

2018年12月02日T14:24:15+00:00

memccpy would return a pointer over the given size when c is not
found in the source buffer and n reaches 0.

fix aliasing-based undefined behavior in string functions

2018年09月26日T18:39:10+00:00

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.

include cleanups: remove unused headers and add feature test macros

use restrict everywhere it's required by c99 and/or posix 2008

2012年09月07日T02:44:55+00:00

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.
