Looking for documentation

[Jochen Manns, PI der Uni Bonn, 732738/3611]

Dear UNIX-Experts,

        can some of you give me some hints on where I can get some
        good - whatever good may be - documentation on:
        - things around writing real and pseudo/STREAMS device drivers
          I'm thinking of things like general strategies, callable
          system routines - especially those not in the man-pages -,
          eventcounters, locking mechanisms and principles and so
          on. Out machine has got a /dev/tcp STREAMS pseudo device
          using the transport layer interface TLI. Is this implementation
          common and is there any PD source on it?
        - how to use TLI
          up to now I used trial and error but that consumes a lot of
          time. How can I learn TLI more efficient? Are there RFCs on
          this topic?
        - is there an index for RFCs?

        We are running UNIX V.3 on a Data General AViiON 300.

Thank you in advance
