-
- Yes, the TLI interface is included for use by HP and third-party
- products supplying STREAMS-based network protocol stacks that
- understand TPI (the downstream end of the TLI interface module).
- HP will not be supplying a STREAMS-based implementation of TCP/IP
- in conjunction with or as part of the HP-UX 9.x releases.

-
- It is possible to translate TLI calls into BSD sockets calls and
- send them down a (non-STREAMS-based) TCP/IP stack. HP is investigating
- something along these lines - anyone interested? (If so, why do you
- prefer TLI to BSD sockets?). Note, of course, that this works only
- if the application's interaction with the network protocol stack is
- genuinely limited to the TLI interface. If the application is using
- STREAMS to insert additional functionality onto the Stream data path,
- this won't help you.
