2011-04-05fix misaligned read on early string termination in strchrRich Felker1-1/+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.
2011-04-03fix serious bug in strchr - char signednessRich Felker1-9/+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.
2011-03-25fix all implicit conversion between signed/unsigned pointersRich Felker6-20/+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.
2011-03-17fix broken wmemchr (unbounded search)Rich Felker1-1/+1
2011-02-26fix missing prototype for strsignalRich Felker1-0/+1
2011-02-24add implementation of memccpy functionRich Felker1-0/+32
2011-02-24fix backwards conditional in stpncpyRich Felker1-1/+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).
2011-02-14more header cleanup and conformance fixes - string.hRich Felker1-0/+1
2011-02-12initial check-in, version 0.5.0v0.5.0Rich Felker60-0/+1054
