+Blt_Tree <I>tree</I><tt> </tt> <tt> </tt> (in)<BR>
+<tt> </tt> <tt> </tt> Tree containing the node. <P>

+<tt> </tt> <tt> </tt> Node to be deleted.
+<H2><A NAME="sect3" HREF="#toc3">Description</A></H2>
+This procedure deletes a given node and all
+it descendants from a tree data object. <P>
+The arguments are as follows:
+
+<DL>
+
+<DT><I>tree</I> </DT>
+<DD>The tree containing the parent node. </DD>
+
+<DT><I>node</I> </DT>
+<DD>Node to be deleted. The node
+and its descendant nodes are deleted. Each node's data values are deleted
+also. The reference count of the Tcl_Obj is decremented. </DD>
+</DL>
+<P>
+Since all tree
+objects must contain at least a root node, the root node itself can't be
+deleted unless the tree is released and destroyed. Therefore you can clear
+a tree by deleting its root, but the root node will remain until the tree
+is destroyed.
+<H2><A NAME="sect4" HREF="#toc4">Returns</A></H2>
+Always returns TCL_OK. Errors generated in a notification
+callbacks are backgrounded (see <B>Tcl_TreeCreateNotifyHandler</B>).
+<H2><A NAME="sect5" HREF="#toc5">Example</A></H2>
+The
+following example deletes the root node. <BR>
+<CODE>Blt_TreeNode root;<BR>
+<P>
+root = Blt_TreeRootNode(token);<BR>
+Blt_TreeDeleteNode(token, root);<BR>
+
+<H2><A NAME="sect6" HREF="#toc6"></CODE>Notifications</A></H2>
+<B>Blt_TreeDeleteNode</B> can trigger tree notify events. You can
+be notified whenever a node is deleted by using the <B>Blt_TreeCreateNotifyHandler</B>.
+ A callback routine is registered that will be automatically invoked whenever
+a node is deleted via <B>Blt_TreeDeleteNode</B> to the tree.
