Does a new socket open for every UDP connection?

Question

I know that with TCP every connection creates a new socket. Does UDP also create a new socket for each connection?

Answer 1

No.

When you receive a message ( recvmsg()), you are informed of the IP address of the partner who sent the message; when you reply ( sendmsg()), you indicate the IP address the message goes to. This is done through one socket. See also <sys/socket.h>.
