Question

Consider socket API on a Linux machine that supports connected UDP sockets. A connected UDP socket is a UDP socket on which connect function has already been called. Which of the following statements is/are CORRECT?
I. A connected UDP socket can be used to communicate with multiple peers simultaneously.
II. A process can successfully call connect function again for an already connected UDP socket.

• A. II only
• B. Both I and II
• C. Neither I nor II
• D. I only

Answer 1

The correct option is A II only

Bind ( ) function creates local address.
connect ( ) function is specifying remote address.
An unconnected UDP socket is just a Bind ( ) function
A connected UDP socket is one more step above i.e. connect ( ) function [Just behaves like TCP]
