Thank you very much.
It does work!

Hi Sean, your codes can be compiled on Neutrino 6.5.0, but not on 6.3.2.
It gives an error that aggregate "struct ifdatareq ifdr" incomplete type 
cannot be initialized.
I open /usr/include/net/if.h and found that it doesn't define struct 
ifdatareq and the macro SIOCGIFDATA.
How to make it run ok on 6.3.2?
