Object wait

[GnG]

Hi plp..
I'm having some problems with overhead in my thread, when I use the sleep with 2 seconds it does not happen, but when I use the "fast mode", 1 millisecond the problem occurs.

This thread are checking a queue, so if there're no elements, it check again, at Java i resolve it with the .wait() and notifyAll() command, but in C++ I don't know.

What can I do to resolve it?!

Thanks all.

What thread library are you using?

I think you need to read up on 'condition variables' for whatever library it is.

Yeah man,
Condition variables resolved my problem.

PS. I'm using boost thread library.

Thanks.
