How to view all spinlocks in the system?

Burkhardt_BraunBurkhardt_Braun Member Posts: 11

Dear Readers,
the short version:
I want to see all spinlocks in the system ( Windows 7 ). How can I do that?

The long version:
I have a spinlock declared global like this
KSPIN_LOCK SpinLock = 0;
I use it like this
and I can see ( in the memory windows i.e. ) that the contention count is 1.

But whatever I do I can not see it with any** !locks** command and if
I use an** !object** call on the SpinLock I receive a "Not a valid object (ObjectType invalid)"

What to do to show my own spinlock?
