Unix网络编程

Question

I want to send the two different packets in different port numbers parallely using UDP. Can I achive this using single socket() or should I create another socket?? Can anbody give me some idea on this.

Thanks in advance

Answer 1

You can use a single socket, you will be using the system calls sendto(2) and recvfrom(2) to send and receive data over the datagram sockets.

Take a look at https://beej.us/guide/bgnet/html/multi/syscalls.html for more information (the entire guide is definitely worth the read).
