       Blt_TreeNodeId - Returns the node serial number.

SYNOPSIS

       #include <bltTree.h>

       unsigned int
       Blt_TreeNodeId(node)

ARGUMENTS

       Blt_TreeNode   node   (in)      Node whose ID is to be returned.

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
       programming 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));
