Subject: fix clock_nanosleep error case
X-Git-Tag: v1.1.16~49
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=3ca2d2d4aef910663785fe232d7d2127a22d8a84;p=oweals%2Fmusl.git

fix clock_nanosleep error case

posix requires that EINVAL be returned if the first parameter specifies
the cpu-time clock of the calling thread (CLOCK_THREAD_CPUTIME_ID).
linux returns ENOTSUP instead so we handle this.
