2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker1-1/+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.
2012-04-16wordexp must set the we_offs entries of we_wordv to null pointersRich Felker1-0/+4
2012-04-16fix crash in wordfree if we_offs is not initialized by the callerRich Felker1-0/+2
I'm not sure if it's legal for wordexp to modify this field, but this is the only easy/straightforward fix, and applications should not care. if it's an issue, i can work out a different (but more complex) solution later.
2011-06-25wordexp cannot use we_offs unless WRDE_DOOFFS flag is setRich Felker1-1/+2
previously, a potentially-indeterminate value from we_offs was being used, resulting in wrong we_wordc and subsequent crashes in the caller.
