For what it's worth, NetBSD has the below. I found the names
in FreeBSD
perforce using Google and used them in the hope of being
compatible. 
I didn't find equivalents in other systems when I looked.

int     pthread_mutex_held_np(pthread_mutex_t *);
int     pthread_rwlock_held_np(pthread_rwlock_t *);
int     pthread_rwlock_wrheld_np(pthread_rwlock_t *);
int     pthread_rwlock_rdheld_np(pthread_rwlock_t *);
