* fix some more O_CLOEXEC/SOCK_CLOEXEC issuesRich Felker2012-09-291-1/+1

* 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.
* fix memory leak on failure in realpathRich Felker2011-06-181-4/+4

* minimal realpath implementation using /procRich Felker2011-04-171-0/+43
| | | | | | | clean and simple, but fails when the caller does not have permissions to open the file for reading or when /proc is not available. i may replace this with a full implementation later, possibly leaving this version as an optimization to use when it works.
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+6
