       Blt_TreeNodeId - Returns the node serial number.

SYNOPSIS

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));
