67 Once a thread has been detached, it can't be joined with

71 A new thread can be created in a detached state using
72 .BR pthread_attr_setdetachstate (3)
73 to set the detached attribute of the

78 The detached attribute merely determines the behavior of the system

80 it does not prevent the thread from being terminated
81 if the process terminates using

89 should be called for each thread that an application creates,
