WAIT_FOR_COMPLETION_(9) 					   Driver Basics					   WAIT_FOR_COMPLETION_(9)

NAME

       wait_for_completion_timeout - waits for completion of a task (w/timeout)

SYNOPSIS

       unsigned long __sched wait_for_completion_timeout(struct completion * x, unsigned long timeout);

ARGUMENTS

       x
	   holds the state of this particular completion

       timeout
	   timeout value in jiffies

DESCRIPTION

       This waits for either a completion of a specific task to be signaled or for a specified timeout to expire. The timeout is in jiffies. It is
       not interruptible.

NAME

       schedule_hrtimeout_range - sleep until timeout

SYNOPSIS

       int __sched schedule_hrtimeout_range(ktime_t * expires, unsigned long delta, const enum hrtimer_mode mode);

ARGUMENTS

       expires
	   timeout value (ktime_t)

       delta
	   slack in expires timeout (ktime_t)

       mode
	   timer mode, HRTIMER_MODE_ABS or HRTIMER_MODE_REL

DESCRIPTION

       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).

       The delta argument gives the kernel the freedom to schedule the actual wakeup to a time that is both power and performance friendly. The
       kernel give the normal best effort behavior for "expires+delta", but may decide to fire the timer earlier, but no earlier than expires.

       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
