If .Fa thread has not terminated, .Fn pthread_detach will not cause it to terminate. The effect of multiple .Fn pthread_detach calls on the same target thread is unspecified. .Sh RETURN VALUES If successful, the .Fn pthread_detach function will return zero. Otherwise an error number will be returned to indicate the error. Note that the function does not change the value of errno as it did for some drafts of the standard. These early drafts also passed a pointer to pthread_t as the argument. Beware! .Sh ERRORS .Fn pthread_detach will fail if: .Bl -tag -width Er .It Bq Er EINVAL The implementation has detected that the value specified by .Fa thread does not refer to a joinable thread. .It Bq Er ESRCH No thread could be found corresponding to that specified by the given thread ID, .Fa thread . .El .Sh SEE ALSO .Xr pthread_join 3 .Sh STANDARDS .Fn pthread_detach conforms to .St -p1003.1-96 .
