WAIT_EVENT_INTERRUPT(9) 					   Driver Basics					   WAIT_EVENT_INTERRUPT(9)

NAME

       wait_event_interruptible_hrtimeout - sleep until a condition gets true or a timeout elapses

SYNOPSIS

       wait_event_interruptible_hrtimeout(wq, condition, timeout);

ARGUMENTS

       wq
	   the waitqueue to wait on

       condition
	   a C expression for the event to wait for

       timeout
	   timeout, as a ktime_t

DESCRIPTION

       The process is put to sleep (TASK_INTERRUPTIBLE) until the condition evaluates to true or a signal is received. The condition is checked
       each time the waitqueue wq is woken up.

       wake_up has to be called after changing any variable that could change the result of the wait condition.

       The function returns 0 if condition became true, -ERESTARTSYS if it was interrupted by a signal, or -ETIME if the timeout elapsed.

NAME

       clear_wait - General: Clears the wait condition

SYNOPSIS

       void clear_wait(
	       thread_t thread,
	       int result,
	       boolean_t interrupt_only );

ARGUMENTS

       Specifies  a  pointer  to  the thread Specifies the outcome of the wait. You can pass one of the following values: This is a normal wakeup.
       The timeout period expired.  The clear_wait routine interrupted the wakeup.  Specifies a Boolean value that indicates  how  the	clear_wait
       routine clears the wait condition. You can pass one of the following values: Clears the wait condition only if the kernel thread is waiting
       in an interruptible state.  Clears the wait condition under any circumstances.

DESCRIPTION

       The clear_wait routine clears the wait condition for the specified kernel thread and starts executing the kernel thread, if appropriate. If
       the  kernel  thread is interruptible and is still waiting for the event, clear_wait sets the kernel thread state to TH_RUN and places it on
       the run queue.

RETURN VALUES

       None
