Hi Michael, Why it should be a special case about pthread that we should mention that all resources are freed on process termination which is feature of an Operating system. When we don't mention it in open.2 or free.3, I thought it should not be mentioned in pthread case, as it is something not related to it. The sentence in bracket looks more confusing if we read previous one. "Either pthread_join(3) or pthread_detach() should be called for each thread that an application creates, so that system resources for the thread can be released. (But note that the resources of all threads are freed when the process terminates.)" I think above sentences convey that you should call either pthread_join() or pthread_detach() so that resources are can be freed. But note that those won't get freed until process is terminated. That's why it looks confusing to me and looks invalid because note in bracket conveys different meaning than intended.
