Routine Description:

    Performs the first step in the creation of a registry key.  This
    routine checks to make sure the caller has the proper access to
    create a key here, and allocates space for the child in the parent
    cell.  It then calls CmpDoCreateChild to initialize the key and
    create the key object.

    This two phase creation allows us to share the child creation code
    with the creation of link nodes.

Arguments:

    Hive - supplies a pointer to the hive control structure for the hive

    Cell - supplies index of node to create child under.

    AccessState - Running security access state information for operation.

    Name - supplies pointer to a UNICODE string which is the name of
            the child to be created.

    AccessMode - Access mode of the original caller.

    Context - pointer to CM_PARSE_CONTEXT structure passed through
                the object manager

    BaseName - Name of object create is relative to

    KeyName - Relative name (to BaseName)

    Object - The address of a variable to receive the created key object, if
             any.

Return Value:

Routine Description:

    Creates a new sub-key.  This is called by CmpDoCreate to create child
    sub-keys and CmpCreateLinkNode to create root sub-keys.

Arguments:

    Hive - supplies a pointer to the hive control structure for the hive

    ParentCell - supplies cell index of parent cell

    ParentDescriptor - Supplies security descriptor of parent key, for use
           in inheriting ACLs.

    AccessState - Running security access state information for operation.

    Name - Supplies pointer to a UNICODE string which is the name of the
           child to be created.

    AccessMode - Access mode of the original caller.

    Context - Supplies pointer to CM_PARSE_CONTEXT structure passed through
           the object manager.

    BaseName - Name of object create is relative to

    KeyName - Relative name (to BaseName)

    Flags - Supplies any flags to be set in the newly created node

    KeyCell - Receives the cell index of the newly created sub-key, if any.

    Object - Receives a pointer to the created key object, if any.

Return Value:

    STATUS_SUCCESS - sub-key successfully created.  New object is returned in
            Object, and the new cell's cell index is returned in KeyCell.

    !STATUS_SUCCESS - appropriate error message.
