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. Note that the function does not change the value 59of errno as it did for some drafts of the standard. These early drafts 60also passed a pointer to pthread_t as the argument. Beware! 61.Sh ERRORS 62.Fn pthread_detach 63will fail if: 64.Bl -tag -width Er 65.It Bq Er EINVAL 66The implementation has detected that the value specified by 67.Fa thread 68does not refer to a joinable thread. 69.It Bq Er ESRCH 70No thread could be found corresponding to that specified by the given 71thread ID, 72.Fa thread . 73.El 74.Pp 75.Sh SEE ALSO 76.Xr pthread_join 3 77.Sh STANDARDS 78.Fn pthread_detach 79conforms to ISO/IEC 9945-1 ANSI/IEEE 80.Pq Dq Tn POSIX 81Std 1003.1 Second Edition 1996-07-12. 82
