wait_event_interruptible() didn't work as I expected.

[=?euc-kr?B?sei9wsf2?= <shkim7@web.dwe.co.kr>]

Hi,

Does anyone out there know how to use
wait_event_interruptible(wq,condition) correctly?

I thought the code below,
          timeout = jiffies + ticks;
          wait_event_interruptible(wq, jiffies > timeout);
could take the place of 
          interruptible_sleep_on_timeout(&wq, ticks);

but it was just blocked at schedule(); in wait_event_interruptible() macro
and didn't move out of it.
why?

as a matter of fact, i have to implement 
             down_interruptible_timeout(&sem, ticks);

and i thought,
         wait_event_interruptible(wq, (jiffies > timeout) ||
!down_trylock(&sem));
would do, but it didn't work, (the process was put to sleep until it was
given a signal.)

maybe It's because I have no big understanding of how schedule() works.
I would be very grateful if you could help me with this.
