I am writing a clock application (MultiFinder aware) and I have a problem how
to check an alarm. The current version is I keep comparing the alarm againts
the current time while I am idle (no event pending).

My questions are :
	How do you check the alarm in the most efficient way? 
	By this I mean I won't miss the alarm no matter where I am or what
	other programs are doing (in background, in foreground).

	If I have to use clock/time interrupt, how could I do it? (sample
	of code will be appreciated). What documentation do I have to read?

Thank you very much in advance.
