He's programming in userspace. :)

You need to call xc_interface_open() to get an xc_handle.  Please read
through the rest of xenctrl.h before asking any more coding questions
here.  You could also have found the answer by looking at any of the
other programs in the tools/ directore that use the xc interface. 

Cheers,
