Hi Adnan,

There is documentation about how to use a USRP- object in the doxygen- 
generated api- pages at
http://gnuradio.org/doc/doxygen/index.html

I haven't found that much code that is c++- specific in the usrp- 
objects, although I saw a note some time ago
about the possibility to template the usrp2- data handler.

In any case you should look into the usrp_{source | sink}_x classes.

There is a lack of c/c++ examples in the gnuradio source- tree, but the 
swig- mapping of functions from c++ to python is straight forward. You
should be able to look at how USRPs are set up in Python and do almost 
the same thing in c/c++.
