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 several times but couldn't find proper way to get IP address from sock structure.

I believe this is a way to get IP from sock struct after server accept request from client. More specifically in c after server execute 

```
csock = accept(ssock, (struct sockaddr *)&client_addr, &clen) 

```

Thanks
