If 48.Fa thread 49has not terminated, 50.Fn pthread_detach 51will not cause it to terminate. The effect of multiple 52.Fn pthread_detach 53calls on the same target thread is unspecified. 54.Sh RETURN VALUES 55If successful, the 56.Fn pthread_detach 57function will return zero. Otherwise an error number will be returned to 58indicate the error. 59.Sh ERRORS 60.Fn pthread_detach 61will fail if: 62.Bl -tag -width Er 63.It Bq Er EINVAL 64The implementation has detected that the value specified by 65.Fa thread 66does not refer to a joinable thread. 67.It Bq Er ESRCH 68No thread could be found corresponding to that specified by the given 69thread ID, 70.Fa thread . 71.El 72.Pp 73.Sh SEE ALSO 74.Xr pthread_join 3 75.Sh STANDARDS 76.Fn pthread_detach 77is expected to conform to IEEE 78.Pq Dq Tn POSIX 79Std 1003.1c when it is published. 80
