I am learning OpenMP parallel processing library in C++. I felt that I got the basic concepts, and try to test my knowledge by implementing a linked list queue. I wanted to consume the queue from multiple threads.

The challenge here is that not to consume the same node twice. So I was considering sharing the queue between threads but allowing only a single thread to update(go to the next node in the queue) it at a time. For this purpose, I could use critical or lock. However, without using them; somehow, it seems to be working perfectly. No race-condition has occurred.
