Or if we cannot restrict from inode number getting changed , is there any way to identify the file uniquely as inode number does.
I need a way to differentiate between a.txt that is modified and a.txt that was created after renaming the earlier a..txt to a.txt.1
Kindly reply
Thanks in Advance.

If there are multiple links to a file,
vi file should not change the i-node number. If there is only one link to a file and you make any changes to the file using
vi, it is more efficient to rename the temp file to the final resting place rather than copy the temp file onto the original file and then remove the temp file.
Why do you care if the i-node number changes? Why isn't the file's name (
a.txt) sufficient for identifying the file?
(Note that
ls -i and
ls -li will also give you the i-node number even on systems that don't have the
stat utility.)

Blt_TreeNodeId(3) BLT Library Procedures Blt_TreeNodeId(3)
__________________________________________________________________________________________________________________________________________________
NAME
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
", Blt_TreeNodeId(node));
