65 Once a thread has been detached, it can't be joined with
67 or be made joinable again.
69 A new thread can be created in a detached state using
70 .BR pthread_attr_setdetachstate (3)
71 to set the detached attribute of the

76 The detached attribute merely determines the behavior of the system

78 it does not prevent the thread from being terminated
