Subject: support: Add xclock_now helper function.
X-Git-Tag: glibc-2.30~78
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=db13e32cb8d5f74fe61880459c7ddf8f47da436b;p=thirdparty%2Fglibc.git

support: Add xclock_now helper function.

It's easier to read and write tests with:

 const struct timespec ts = xclock_now(CLOCK_REALTIME);

than

 struct timespec ts;
 xclock_gettime(CLOCK_REALTIME, &ts);

	* support/xtime.h: Add xclock_now() helper function.
