- int __sched schedule_hrtimeout(ktime_t * expires, const enum hrtimer_mode mode);
- timeout value (ktime_t)
- timer mode, HRTIMER_MODE_ABS or HRTIMER_MODE_REL
Make the current task sleep until the given expiry time has elapsed. The routine will return immediately unless the current task state has been set (see set_current_state).
You can set the task state as follows -
TASK_UNINTERRUPTIBLE - at least timeout time is guaranteed to pass before the routine returns.
TASK_INTERRUPTIBLE - the routine may return early if a signal is delivered to the current task.
The current task state is guaranteed to be TASK_RUNNING when this routine returns.
Returns 0 when the timer has expired otherwise -EINTR
