SYNOPSIS
       #include <bltTree.h>

_________________________________________________________________

DESCRIPTION
       This  procedure returns the node serial number.	The node serial number
       is useful for programs that export the tree data object to the Tcl pro‐
       gramming	 level.	  Since	 node labels (and therefore pathnames) are not
       unique, the ID can be used to uniquely identify a node.

       The arguments are as follows:

       node	 The node whose serial number is returned.  The serial	number
		 of the root node for example is always 0.

RETURNS
       The  serial number of the node.	Nodes are given a unique serial number
       when they are created.  You can use the ID to later retrieve  the  node
       using Blt_TreeGetNode.

EXAMPLE
       The following example prints the ID of a node.

	      printf("root ID is %s\n", Blt_TreeNodeId(node));

KEYWORDS
       Tcl_TreeCreateNode, Tcl_TreeDeleteNode
