New Interfaces

The IETF's IPng working group and the POSIX p1003.1g working group have made a good bit of progress in identifying and standardizing new APIs needed to develop protocol-independent programs. Beyond this, the NRL IPv6 implementation found several other interfaces that we felt needed to be present in order to develop fully functional protocol-independent applications. In many cases, the BSD sockets interfaces were almost good enough but in practice misused. The new interfaces extend many BSD interfaces and supersede others.

The new interfaces break down into roughly two categories. The first are functions to perform name resolution operations (name to addresses, address to name) in a clean way. The second are operations to help use socket addresses (sockaddrs) in a clean way.
