Hi all.
Suppose I've got two sockets, A and B, and I'd like to make it so all
data that arrives on B gets sent to A. My program does not care about
the transferred data (and never will), and should handle roughly 5000
such A/B socket pairs.
I think it's possible to use a combination of tee()/split() to get the
(non-)buffering done in the kernel, but it seems that my program's
level of indifference towards the data admits an even higher-level
mechanism of forwarding the data from B to A.
How can this be done without explicitly copying the data in my program?
Thanks.
