I think this may actually be a GLIBC question, so you might want to hit up those people. Then again since it may use "-lrpc" then it might be RedHat.
It also might be worth hitting Sun up, who's getting more into the Linux world.
I would be interested if you hear anything new though.
Sorry and thanks,

Hi Matt,
Thanks for the reply.
But when will the linux RPC code be updated ?? I wander how enterprise applications using RPC currently run without threading. Do Linux guys have any plans to Incorporate the latest TLI ? Is there any other place (I mean among the linux internal developers or the guys who have implemented SUN RPC on LINUX) where I can raise this issue?
Do you have any idea how to change the svc code to support threading or where can I get help to do so?
Thanks & Regards
Ashish

Linux's RPC code appears to be based on a very old iteration of SunRPC that was put into public domain quite some time ago. The later revs, which are not public domain, included support for (actually the migration to) TLI with protocol independence. Subsequently TLI was stillborn, but whatever.
In any case, as far as I know only Sun's RPC intrinsically supports threads. I have never seen another implementation that does.
You can do your own threading, if nothing else by editing the generated files, but it's not clear that the RPC routines themselves are thread safe - in fact I would guess they are not based on the fact that they usual a lot of global data.
Personally I'd love to see a thread safe RPC for Linux, but it's probably not worth the effort. A better bet would be to maybe use XML RPC if you can (though that! doesn't seem to have the same depth of capabilities).
Unfortunately, to get threading, you'll probably either have to add a lot of hacks, or write your own socket code and API getting rid of RPC.
