registryManager.h

The file registryManager.h defines the three data structures and 12 functions required to implement registry key hiding. There is one KEY_HANDLE list. Each mapped key has one KEY_HANDLE entry containing one REG_KEY_DATA entry as well as one SUBKEY_DATA entry for every subkey of the given key. These subkey entries hold the key indices that will be passed back to the operating system. Key hiding is accomplished by aligning key indices to skip selected keys.
