Timer Elapse Question.

I have a question about Timers. When does a timers call back function get called in respect to other currently executing functions.

Lets say I have a LinkedList and I want to add a new item to it, but my timer has elapsed and is iterating through that list already.

Are timers and their call backs being handled in a seperate thread? If they aren't then this wouldn't be a problem. If so I'd have to add some sort of lock on the linked list to insure the integrity of its data. I looked around and couldn't find any info so some help would be appreciated.

one thread at time.

if you already iterating list, no function will execute before you finished.

metadata for every list will solve problem.

Not sure what you mean by metadata for the list but thanks. Is there any case i need to worry about multi threaded programming because i recall reading somewhere about a thread per player or some such.

Nope, wc3 doesn't have any multi-threading.

Awesome thanks. Glad to hear that heh.
