None of the following constants in time.h are guarded by
__BSD_VISIBLE, __FreeBSD__, etc, even though other sections of the
file are blocked off that way (and the comments suggest that they're
FreeBSD-specific). I was wondering why that's the case...
#define CLOCK_UPTIME 5 /* FreeBSD-specific. */
#define CLOCK_UPTIME_PRECISE 7 /* FreeBSD-specific. */
#define CLOCK_UPTIME_FAST 8 /* FreeBSD-specific. */
#define CLOCK_REALTIME_PRECISE 9 /* FreeBSD-specific. */
#define CLOCK_REALTIME_FAST 10 /* FreeBSD-specific. */
#define CLOCK_MONOTONIC_PRECISE 11 /* FreeBSD-specific. */
#define CLOCK_MONOTONIC_FAST 12 /* FreeBSD-specific. */
#define CLOCK_SECOND 13 /* FreeBSD-specific. */
Also, they're blocked off by #if !defined(CLOCK_REALTIME) &&
__POSIX_VISIBLE >= 200112 , which doesn't seem to make sense, given
that it's an "advanced realtime" feature, according to POSIX 2008.
Thanks!
