49 function suspends execution of the calling thread until the target
51 terminates unless the target
53 has already terminated.
55 On return from a successful
59 argument, the value passed to
61 by the terminating thread is stored in the location referenced by
65 returns successfully, the target thread has been terminated.
67 of multiple simultaneous calls to
69 specifying the same target thread are undefined.
72 is cancelled, then the target thread is not detached.
74 A thread that has exited but remains unjoined counts against
75 [_POSIX_THREAD_THREADS_MAX].
79 function will return zero.
80 Otherwise an error number will be returned to
85 function will fail if:
88 The implementation has detected that the value specified by
90 does not refer to a joinable thread.
92 No thread could be found corresponding to that specified by the given
96 A deadlock was detected or the value of
98 specifies the calling thread.
