Module Name:

    regkey.hxx

Abstract:

    This module contains the declarations for the REGISTRY_KEY_INFO class.
    REGISTRY_KEY_INFO is class that contains all the information of a
    registry key, sucha as:

        -Key Name
        -Title Index
        -Class
        -Security Attribute
        -Last Write Time
        -Number of Sub-keys
        -Number of Value Entries

    A REGISTRY_KEY_INFO object is reinitializable.
