I need access to the AppleTalk protocols on Ethernet on a Sun network.
I noticed an AF_APPLETALK address family in the sys/socket.h header,
but on further invesigation discovered that Sun don't provide it with
the standard release and aren't ever likely to, probably because it
already exists inside Tops. On asking a Tops person how to get at
the protocols, I was told that the implementation is never likely
to become public, ie you are stuck with the software Tops provides
and can't ever write your own.
What I would like to know is (a) has anyone else implemented the
protocols who is prepared to be a little more open about things, or
(b) has anyone else fallen into this problem, and if so, was it easy
to solve; as far as I can see, if the AF_APPLETALK family is supported
under Tops, it should be possible to invoke socket() &c., provided you
know the address and data formats (big `provided').
Incidentally, I don't see that this should upset anyone, since I have
to buy Tops *anyway* in order to access the modified kernel for the
AppleTalk protocol family.
Any help much appreciated.
