* fix false negatives with periodic needles in strstr, wcsstr, and memmemRich Felker2014-04-181-1/+1
| | | | | | | | in cases where the memorized match range from the right factor exceeded the length of the left factor, it was wrongly treated as a mismatch rather than a match. issue reported by Yves Bastide.
* include cleanups: remove unused headers and add feature test macrosSzabolcs Nagy2013-12-121-3/+0

* use restrict everywhere it's required by c99 and/or posix 2008Rich Felker2012-09-061-1/+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.
* remove buggy short-string wcsstr implementation; always use twowayRich Felker2012-08-111-9/+0
| | | | | | since this interface is rarely used, it's probably best to lean towards keeping code size down anyway. one-character needles will still be found immediately by the initial wcschr call anyway.
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+117
