Hi,

I have a common question about locks:

class SetPointer
{
private:
        void *ptr;

        MY_LOCK lock;


public:
        void SetPointer(void *p)
        {
                Lock(this->lock);
                this->ptr = p;
        }

        void *GetPointer()
        {
                Lock(this->lock);
                return this->ptr;
        }
};


Just a question, is this lock redundant, when the Pointer can be set/
get from different threads?
Thanks a lot!! Bye, moerchendiser2k3

1. That's C++. What does it have to do with Python?

2. The value you're accessing is a simple pointer which you're either
setting or getting, so a lock shouldn't be necessary.

3. You're locking, but never unlocking. The sequence should be: lock, do
stuff, unlock.
