Subject: fix errno behavior in clock_* functions
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=1b538acb0ac8520a8a5fd828add2e52e1d2a41eb;hp=1b538acb0ac8520a8a5fd828add2e52e1d2a41eb;p=musl

fix errno behavior in clock_* functions

these functions are specified inconsistent in whether they're
specified to return an error value, or return -1 and set errno.
hopefully now they all match what POSIX requires.
