You need to put that into shared memory so that all instances of your DLL
have access to it.

You need to export your callback function.

The DLL should not be performing the unhooking automatically.  The main
application that originally set the hook should be the only one that
releases the hook as well.  This is because your DLL will be loaded by
multiple processes, so you don't want the DLL to release the hook every time
a process terminates.
