How to get ip address from sock structure in c?

Question

I\'m writing simple server/client and trying to get client IP address and save it on server side to decide which client should get into critical section. I googled it severa

Answer 1

The easier and correct way for extracting IP address and port number would be:

printf("IP address is: %s\n", inet_ntoa(client_addr.sin_addr));
printf("port is: %d\n", (int) ntohs(client_addr.sin_port));
