Hi Jeff, Thanks for your response.
Actually requirement is how a C/C++ program running in "master" node should find out whether "slave" node is reachable (as we check this using "ping" command) or not ? Because IP address may change at any time, that's why I am trying to achieve this using "host name" of the "slave" node. How this can be done?
