I am learning about sockets in C, and I just learned that you can connect an UDP socket (and its consequences) through this piece of documentation from IBM.
My question is: How popular are UDP connected sockets nowadays, and what could be an example of its usage over unconnected UDP sockets?

CodePudding user response：

They are essentially the same sockets, just accessed with different function calls. If you only intend to communicate with one address, then you might find it more convenient to use a connected socket, so that you don't need to give the address to each send call, and you don't need to check the address when receiving.
