返回类型：

参数：无

131  当:which_clock恒等于The IDs of the various system clocks (for POSIX.1b interval timers):
132  当:which_clock恒等于CLOCK_MONOTONIC
133  当:which_clock恒等于CLOCK_BOOTTIME
134  退出
135  默认
136  返回:负EINVAL
139  如果get_timespec64( & t, rqtp)则返回:负EFAULT
141  如果非Returns true if the timespec64 is norm, false if denorm:则返回:负EINVAL
143  如果prefix, newline flags 按位与The various flags for setting POSIX.1b interval timers:则rmtp = NULL
145  type等于如果rmtp则TT_NATIVE否则TT_NONE
146  rmtp等于rmtp
147  返回:hrtimer_nanosleep( & t, prefix, newline flags & The various flags for setting POSIX.1b interval timers: ? Time value is absolute : Time value is relative to now, which_clock)
