I'm having second thoughts about this one. There is a significant
risk of false positives if the mutex is currently locked by another
thread. I'm wondering whether to a) change the implementation so it
only returns true if the mutex is owned by the current thread, or b)
change the interface so you can specify a specific thread, or NULL
for "any".
Please don't do the latter. Semantically the right thing to do here
is to assert if the curthread owns the lock or not. Any lock should
not be interested on what is the state in regard of other locks.
Thank you. That was my thought as well, but I didn't want to exclude
the alternative without discussion.
Then please change the API so that it is pthread_mutex_isowned_np().
