Because it is more obvious that _isowned() is for the current thread than _islocked(). As you can tell by my previous (incorrect)=20 assumption. There is prior art for this outside of FreeBSD. Solaris has mutex_owned() as part of their kernel mutex API. I would suggest using pthread_mutex_owned_np(). Hmm, even FreeBSD has mtx_owned() :-) --=20 DE ---559023410-684387517-1202142669=:13899--
