Hi Ashwin,

I havent worked on invokinng custom native calls from GUI., but some
test .out apps..

As Dianne said below, my procedure was similar..
 - i will have a newly added shared library written with all native
implementation (includes kernel ioctl calls, other native components)
 - link the .so to my .out, load the library and start using it.
