If you can show me a snippet of user-space code similar to the
complexity of what I posted earlier, I'll actually do a benchmark
against it and my code to see if they are roughly equal. If so, I'll
purge this from my patch set and never bother anyone with it again...
On the other hand, if it requires hard to find and/or half-assed libraries
and lots of code, don't bother.
Well, i can give you pointers and if you are really serious you will
invest the time.
- use iproute2 and see how one dumps netdevice stats
- Continue by looking at iproute2/ip/
files iplink.c and ipaddress.c
and note that:
stats are stored in a TLV IFLA_STATS and are printed in
print_linkinfo()
The code is not much to study if you are serious about performance.
Thomas Graf as well has been trying to make it simpler to do this kind
stuff. I havent looked at it lately but should make it simpler.
If you can beat the performance of that with your half-assed tool
then i will be interested in showing up. For now you are on your own on
or maybe someone else has time.
Looks about as complex as last time I looked..lots of MACROs, constants,
and powerful options that might make good sense for 'ip', but make using
it in a stand-alone application difficult.
I also notice that the lib/libnetlink.c file is GPL instead of LGPL,
so I can't use it in my application anyway...
