   NwNdsAddObject()

   This function is used to add a leaf object to an NDS directory tree.

   Arguments:

       HANDLE           hParentObject - A handle to the parent object in
                        the directory tree to add a new leaf to. Handle is
                        obtained by calling NwNdsOpenObject.

       LPWSTR           szObjectName - The directory name that the new leaf
                        object will be known by.

       HANDLE           hOperationData - A buffer containing a list of
                        attributes and values to create the new object. This
                        buffer is manipulated by the following functions:
                            NwNdsCreateBuffer (NDS_OBJECT_ADD),
                            NwNdsPutInBuffer, and NwNdsFreeBuffer.

    Returns:

   This function is used to change the password for a given user object
   in a NDS directory tree.

   Arguments:

       HANDLE           hUserObject - A handle to a specific user object in
                        the directory tree to change the password on. Handle
                        is obtained by calling NwNdsOpenObject.

       LPWSTR           szOldPassword - The current password set on the user
                        object hUserObject.

   NwNdsListSubObjects()

   This function is used to enumerate the subordinate objects for a particular
   parent object. A filter can be passed in to restrict enumeration to a
   a specific class type or list of class types.

   Arguments:

       HANDLE           hParentObject - A handle to the object in the directory
                        tree whose subordinate objects (if any) will be
                        enumerated.

       DWORD            dwEntriesRequested - The number of subordinate objects
                        to list. A subsequent call to NwNdsListSubObjects will
                        continue enumeration following the last item returned.

       LPDWORD          lpdwEntriesReturned - A pointer to a DWORD that will
                        contain the actual number of subobjects enumerated in
                        the call.

       LPNDS_FILTER_LIST lpFilters - The caller can specify the object class
                         names for the kinds of objects that they would like
                         to enumerate. For example if just User and Group
                         object classes should be enumerated, then a filter
                         for class names NDS_CLASS_USER and NDS_CLASS_GROUP
                         should be pass in.

                                - or -

                         NULL to indicate that all objects should be returned
                         (no filter).

       HANDLE *         lphOperationData - Address of a HANDLE handle to
                        receive created buffer that contains the list of
                        subordinate objects read from the object
                        hParentObject. This handle is manipulated by the
                        following functions:
                           NwNdsGetObjListFromBuffer and NwNdsFreeBuffer.

/*
   NwNdsModifyObject()

   This function is used to modify a leaf object in an NDS directory tree.
   Modifying a leaf object means: changing, adding, removing, and clearing of
   specified attributes for a given object.

   Arguments:

       HANDLE           hObject - A handle to the object in the directory
                        tree to be manipulated. Handle is obtained by calling
                        NwNdsOpenObject.

       HANDLE           hOperationData - A handle to data containing a
                        list of attribute changes to be applied to the object.
                        This buffer is manipulated by the following functions:
                           NwNdsCreateBuffer (NDS_OBJECT_MODIFY),

/*
   NwNdsPutInBuffer()

   This function is used to add an entry to the buffer used to describe
   an object attribute or change to an object attribute. The buffer must
   be created using NwNdsCreateBuffer. If the buffer was created using the
   operations, NDS_OBJECT_ADD, NDS_SCHEMA_DEFINE_CLASS,
   NDS_SCHEMA_READ_ATTR_DEF, or NDS_SCHEMA_READ_CLASS_DEF, then
   dwAttrModificationOperation is ignored. If the buffer was created using
   either the operation NDS_OBJECT_READ or NDS_SEARCH, then
   dwAttrModificationOperation, puAttributeType, and lpAttributeValue are
   all ingnored.

   Arguments:

       LPWSTR           szAttributeName - A NULL terminated WCHAR string
                        that contains name of the attribute value to be
                        added to the buffer. It can be a user supplied
                        string, or one of the  many defined string macros
                        in ndsnames.h.

       DWORD            dwSyntaxID - The ID of the syntax structure used to
                        represent the attribute value. Syntax IDs and their
                        associated structures are defined in the file
                        NdsSntx.h. According to the NetWare NDS schema spec,
                        there is and always will be, only 28 (0..27)
                        different syntaxes.

       LPVOID           lpAttributeValues - A pointer to the beginning of a
                        buffer containing the value(s) for a particular
                        object attribute with data syntax dwSyntaxID.

       DWORD            dwValueCount - The number of value entries found in
                        buffer pointed to by lpAttributeValues.

       DWORD            dwAttrModificationOperation - If the buffer was created
                        using the operation NDS_MODIFY_OBJECT, then this is
                        used to desribe which type of modification operation
                        to apply for a given attribute. These attribute
                        modification operations are defined near the beginning
                        of this file.

       HANDLE           hOperationData - A handle to data created by
                        calling NwNdsCreateBuffer. The buffer stores the
                        attributes used to define transactions for
                        NwNdsAddObject, NwNdsModifyObject, NwNdsReadObject,
                        NwNdsReadAttrDef, NwNdsReadClassDef, or NwNdsSearch.

/*
   NwNdsSearch()

   This function is used to query an NDS directory tree to find objects of
   a certain object type that match a specified search filter.

   Arguments:

       HANDLE           hStartFromObject - A HANDLE to an object in the
                        directory tree to start search from. Handle is
                        obtained by calling NwNdsOpenObject.

       DWORD            dwInformationType - Indicates whether user chooses to
                        read only the attribute name(s) on the search result
                        objects or read both the attribute name(s) and value(s)
                        from the search result objects.

       DWORD            dwScope -
                        NDS_SCOPE_ONE_LEVEL - Search subordinates from given
                                              object, one level only
                        NDS_SCOPE_SUB_TREE - Search from given object on down
                        NDS_SCOPE_BASE_LEVEL - Applies search to an object

       BOOL             fDerefAliases - If TRUE the search will dereference
                        aliased objects to the real objects and continue
                        to search in the aliased objects subtree. If FALSE
                        the search will not dereference aliases.

       LPQUERY_TREE     lpQueryTree - A pointer to the root of a
                        search tree which defines a query. This tree
                        is manipulated by the following functions:
                           NwNdsCreateQueryNode, NwNdsDeleteQueryNode,
                           and NwNdsDeleteQueryTree.

       LPDWORD          lpdwIterHandle - A pointer to a DWORD that has the
                        iteration handle value. On input, the handle value
                        is set to NDS_INITIAL_SEARCH or to a value previously
                        returned from a prior call to NwNdsSearch. On ouput,
                        the handle value is set to NDS_NO_MORE_ITERATIONS if
                        search is complete, or to some other value otherwise.

       HANDLE *         lphOperationData - The address of a HANDLE to data
                        containing a list of attributes to be read from the
                        objects that meet the search query. This handle is
                        manipulated by the following functions:
                           NwNdsCreateBuffer (NDS_SEARCH),
                           NwNdsPutInBuffer, and NwNdsFreeBuffer.

                                            - OR -

                        The address of a HANDLE set to NULL, which indicates
                        that all object attributes should be read from the
                        search objects found.

                        If these calls are successful, this handle will also
                        contain the read results from the call. In the later
                        case, a buffer will be created to contain the read
                        results. Object information with attribute information
                        can be retrieved from the buffer with the function:
                           NwNdsGetObjectListFromBuffer.

                        After the call to this function, this buffer is ONLY
                        manipulated by the functions:
                          NwNdsGetObjectListFromBuffer,
                          and NwNdsFreeBuffer.

    Returns:

       UNSUCCESSFUL - Call GetLastError for Win32 error code.
