I'm not very good with templates, could you help me understand how it works?

I declared a spinlock variable in my class

        spinlock                    fSpinLock;

then, and the constructor of my class, where I need the spinlock, I added

    // The controller is now in SUSPEND state, we have 2ms to go OPERATIONAL.
    // In order to do so we need a spinlock
    InterruptsSpinLocker spinLocker(fSpinLocker);

... code ...
    spinLocker.Unlock();
... other code of my constructor class ..

but Stefano told me that it should call the Unlock in the destructor when the
object gets out of the scope right ?
