* fix strncat and wcsncat (double null termination)Rich Felker2011-05-223-3/+3
| | | | also modify wcsncpy to use the same loop logic
* fix wcsncpy writing past end of bufferRich Felker2011-05-221-1/+1
|
* function signature fix: add const qualifier to mempcpy src argRich Felker2011-04-261-1/+1
|
* implement memrchr (nonstandard) and optimize strrchr in terms of itRich Felker2011-04-132-4/+15

* fix misplaced *'s in string functions (harmless)Rich Felker2011-04-073-3/+3
|
* fix prototype for strsepRich Felker2011-04-061-0/+1
|
* fix misaligned read on early string termination in strchrRich Felker2011-04-051-1/+2
| | | | | | this could actually cause rare crashes in the case where a short string is located at the end of a page and the following page is not readable, and in fact this was seen in gcc compiling certain files.
* fix serious bug in strchr - char signednessRich Felker2011-04-031-9/+11
| | | | | | search for bytes with high bit set was giving (potentially dangerous) wrong results. i've tested, cleaned up, and hopefully sped up this function now.
* fix all implicit conversion between signed/unsigned pointersRich Felker2011-03-256-20/+16
| | | | | | | sadly the C language does not specify any such implicit conversion, so this is not a matter of just fixing warnings (as gcc treats it) but actual errors. i would like to revisit a number of these changes and possibly revise the types used to reduce the number of casts required.
* fix broken wmemchr (unbounded search)Rich Felker2011-03-171-1/+1
|
* fix missing prototype for strsignalRich Felker2011-02-261-0/+1
|
* add implementation of memccpy functionRich Felker2011-02-241-0/+32
|
* fix backwards conditional in stpncpyRich Felker2011-02-241-1/+1
| | | | | | this only made the function unnecessarily slow on systems with unaligned access, but would of course crash on systems that can't do unaligned accesses (none of which have ports yet).
* more header cleanup and conformance fixes - string.hRich Felker2011-02-141-0/+1

* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-1260-0/+1054
