2. Clean up Struct sockaddr Struct sockaddr_in
Remember all this structure does is specify an address and port.
Family
whatever
2bytes
4 bytes
8bytes
Port
Int address
Unused

3. Client Side Create Socket Connect (blocks, three way handshake)
Send/Receive
Close connection

4. Server
Create socket
Bind socket to port (for a client this is done automatically in connect)
Listen for incoming connection
Accept connection
Send/Receive
Close connection

5. Bind
bind(int socket, struct sockaddr *server_address, unsinged int addresslength)
Remember sockaddr is actually the sockaddr_in struct
Return 0 on success and -1 on fail

6. Listen int listen(int socket, int queue_limit)
Home many people can try and connect at a given time.
Same as bind 0 on success -1 on fail

7. Accept
int accept(int socket, struct sockaddr *clientaddr, unsigned int *addresslength)
Creates a socket for you and doesn’t do anything to your listening socket.
Puts relevant information into clientaddr and addresslength
Success returns the socket descriptor of new socket, on fail return -1

8. Close
Yeah sorry forgot
