hi Greg, yep these mechanisms exist, this is the first things that you
implement when you write a lock system no matter on what: islockable
and islocked
try to understand, what you do (if you use a lck object (locked))
if your lock object has been created, a lock has been aquired
when you create a lock object, the lock system test it for you

Hi mmw, thanks for your reply. I was specifically wondering how I
could do this from a kernel extension? I don't see a header in
Kernel.framework that contains any try_lock functions for lck_mtx_t.
Thanks!

Hmm... I've found this in the sources to xnu, but I can't find this
in
the Kernel.framework. Perhaps I should have mentioned that I'm
writing a kernel extension. Does this exist for kernel extensions,
and if so how do I access it? Right now I'm just linking against
Kernel.framework, which doesn't seem to have this header.
Thanks!
