Re: A clean way to detect if a ldap_pvt_thread_mutex is locked (best would be also to know who's the owner of the lock :)

Duh... please ignore my previous message.  I forgot you said _assert_.

Well, that one isn't hard.
define an ldap_thread_mutex_assert_owner() which is a no-op by default.
Then,

#if LDAP_THREAD_DEBUG_MUTEX

 #if <the specific thread implementation you are using>
  <inspect the mutex structure and do some magic by hand>
 #endif

 Or more generally, use my thr_debug.c package and extend
 ldap_debug_thread_cond_t with the thread ID and info about whether the
 mutex is locked.  Get thread ID with ldap_pvt_thread_self(), compare
 with ldap_pvt_thread_equal().

#endif
