Instead of failing with ENAMETOOLONG, which is swallowed by pthread_set_name_np() anyway, truncate the given name to MAXCOMLEN+1 bytes. This is more likely what the user wants, and saves the caller from truncating it before the call (which was the only recourse). Polish pthread_set_name_np(3) and add a .Xr to thr_set_name(2) so the user might find the documentation for this behavior. Reviewed by: jilles MFC after: 3 days Sponsored by: Dell EMC
