比如这个
function PolledWait takes real duration returns nothing
local timer t
local real timeRemaining
if (duration > 0) then
set t = CreateTimer()
call TimerStart(t, duration, false, null)
loop
set timeRemaining = TimerGetRemaining(t)
exitwhen timeRemaining <= 0
// If we have a bit of time left, skip past 10% of the remaining
// duration instead of checking every interval, to minimize the
// polling on long waits.
if (timeRemaining > bj_POLLED_WAIT_SKIP_THRESHOLD) then
call TriggerSleepAction(0.1 * timeRemaining)
else
call TriggerSleepAction(bj_POLLED_WAIT_INTERVAL)
endif
endloop
call DestroyTimer(t)
endif
endfunction |
