><I
>timeout</I

> jiffies have
elapsed. The routine will return immediately unless
the current task state has been set (see <TT
CLASS="FUNCTION"
>set_current_state</TT
>).
</P
><P
> You can set the task state as follows -
</P
><P
> <TT
CLASS="CONSTANT"
>TASK_UNINTERRUPTIBLE</TT
> - at least <TT
CLASS="PARAMETER"
><I
>timeout</I
></TT
> jiffies are guaranteed to
pass before the routine returns. The routine will return 0
</P
><P
> <TT
CLASS="CONSTANT"
>TASK_INTERRUPTIBLE</TT
> - the routine may return early if a signal is
delivered to the current task. In this case the remaining time
in jiffies will be returned, or 0 if the timer expired in time
</P
><P
> The current task state is guaranteed to be TASK_RUNNING when this
routine returns.
</P
><P
> Specifying a <TT
CLASS="PARAMETER"
><I
>timeout</I
></TT
> value of <TT
CLASS="CONSTANT"
>MAX_SCHEDULE_TIMEOUT</TT
> will schedule
the CPU away without a bound on the timeout. In this case the return
value will be <TT
CLASS="CONSTANT"
>MAX_SCHEDULE_TIMEOUT</TT
>.
</P
><P
> In all cases the return value is guaranteed to be non-negative.
