Migration from IPv4 to IPv6
- System Calls or Bust
- getaddrinfo(): Prepare to launch!
- socket(): Get the File Descriptor!
- bind(): What port am I on?
- connect(): Hey, you!
- listen(): Will somebody please call me?
- accept(): Thank you for calling port 3490
- send() and recv(): Talk to me, baby!
- sendto() and recvfrom(): Talk to me, DGRAM-style
- close() and shutdown(): Get outta my face!
- getpeername(): Who are you?
- gethostname(): Who am I?Porting IPv4 applications to IPv6
- using the correct structures
- INADDR_ANY and INADDR_LOOPBACK
- address and protocol family constants
- IPv6 functions for older IPv4 ones where necessary
- flexible functions that work in both IPv4 and IPv6 environments
- Data structures
- sockaddr_in and in_addr
- in6_addr to store the 128-bit network address
- sockaddr_in6
- To port this code to IPv6
- AF_INET6
- PF_INET6
