How an event case is controlled internally?

[edmonton]

Hi Friends,

I have used event case structure many times in my applications for may years, but I just do not know how an event case is controlled internally. 

An event case structure can have multiple cases, and is enclosed in a while loop. The while loop iterates once only when an event case is occurred, it does not iterate when no case occurs. My question is how often the while loop checks once for all those cases? every millisecond or any other number of millisecond, or even nanosecond?

Thanks,

Gu

For the sake of getting straight to the point, here's a discussion you probably want to read.

Yes, follow the above link.

Just to clarify, the while loop has nothing to with the event structure and does not check or poll anything.
