When I call accept to get a connecting socket, I can get the address of the connection.
E.g.
sockaddr_in addr;
socklen_t addr_size = sizeof(addr);
const int sock = ::accept(main_socket, (sockaddr*)&addr, &addr_size);
// addr.sin_addr stores the address
char addr_str[256];
inet_ntop(addr.sin_family, &addr.sin_addr, addr_str, sizeof(addr_str));
But does the kernel retain the address associated with the socket?
Say I don't save the addr struct and only save sock, is there a function I can call to get the address later?
