Why would I use Sleep() with infinite timeout?

Question

According to MSDN, Sleep() can be provided INFINITE value and that "indicates that the suspension should not time out".

Why would I want to call Sleep() with INFINITE timeout in my program?

Answer 1

I have used Sleep(INFINITE) and it makes perfect sense. I've used it to keep the thread alive. I have registered for WMI notification event (ExecNotificationQueryAsync, which receives event notification infinitely) then you need to keep the application alive. dont' know if this make sense to you.

Answer 2

A sleep with no timeout does not need a timer. This reduces the overhead where you anticipate a variable-length wait but are absolutely sure that the thread will be resumed.
