Interesting, the errno is not even set on macOS according to the man page, at least for pthread_detach
https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/pthread_detach.3.html
"Note that the function does not change the value of errno, as it did for some drafts of the standard. "
So better print the return code there in the error case.
