Its not clear why you are going through the trouble of not passing
your data through the pipe.
Since a pipe has FIFO semantics, and you have small amount of data,
couldn't you just write/read the entire packed data through the pipe,
instead of just a notification byte? Are you not doing this because
you benchmarked performance, and found it to be a bottleneck?
You're already suffering context switching overhead, the memory copy
path through the kernel might not be much worse than the user-space
memory copying you are doing.
Cheers,
Sam
