Hi, I've had to generate some GUIDs for wined3d is there a wine policy on internal GUIDs or should the ones I've generated be ok.
secondly, nothing to do with GUIDS, what's the 'best' thread safe IUnknown enumerate to use for storing a heap of unique elements that will be searched for by the IUnknown pointer as well as emerated.
It would be usefull if the enumerate didn't reference count because I may also need to use a call back or sorts so that when the ref count of the IUnknown gets to zero it's release can tell the enumerate to remove it from the list.

How did you generate them?

Ok, it sounds like you need random removal of objects, so using the list implementation in include/wine/list.h would probably be best. Put any code accessing the list in a critical section and it will be safe. If you want the objects to remove themselves from the list when they are destroyed, then you will have to add a reference to them so that you can use them outside the critical section. Also, you will have to put the adding/releasing references code in a critical section to ensure that there is no race between the refcount going to 0 and the object being removed from the list. Mike and I had to implement something similar to this for the stub manager in dlls/ole32/stubmanager.c so it may be worth having a look at it.
