ExampleSetting an alarm

Set's an alarm at 11 'o clock and tells the player to take the cake out of the oven.

Code

<nowiki>
local myAlarm = os.setAlarm(11)
local event, alarmNumber
while alarmNumber ~= myAlarm do
  event, alarmNumber = os.pullEvent("alarm")
end
print("The cake should be taken out of the oven! Watch out, it is hot!")
    </nowiki>

Eventterminate

Occurs when the user holds down Ctrl-T to terminate the running program. Note that this event is intercepted by os.pullEvent, which handles it by forcefully terminating the program. To handle it, use os.pullEventRaw (or coroutine.yield) instead.

Returns

nil
