Basically what you need to do is
t_kopen()
t_kbind()
t_ksndudata()
t_krcvudata()
look at rtime() in common/rpc/sec/authdesubr.c for a usage example.
We will eventually create a kernel socket interface to make this as
simple as writing a user level socket program.

I'm not sure if this is the correct place to ask, but I am trying to figure out
how to port an old custom in-house streams-based IPC protocol stack to run on
top of UDP instead of raw Ethernet or ATM. I have found a few hints here and
there that it could be done, but no documentation or examples other than trying
to decipher the t_kxxx/tli API calls in the kernel source code.
Basically I need to port our IPC stack to run over UDP because we need to
switch to different hardware since Sun discontinued their ATM adapter and the
new hardware APIs appear to be non-standard and are undocumented. While
documentation to the raw APIs is undocumented, the new hardware does support
running TCP/IP over ATM. By taking advantage of TCP/IP the IPC layer should be
independent of any L2 transport as long as UDP is supported.
Specifically, how do I go about formatting the packets to go over UDP streams to emulate
"sendto" and what format should I expect the received frames to be in? I also
believe I will need to bind to a specific port.
I am pretty new to streams, having spent most of my development efforts in
VxWorks and Linux, though I have been going through the Streams Programming
Guide (which is quite good except for all the formatting errors).
