Test for hdio.c

I am writing a test for hdio.c.
To do so I am calling ioctl as:
`ioctl(fd, HDIO_GETGEO, &geom);`.
Here geom is the geometry struct, and fd is the file descriptor.
Now the problem I am facing is: what should be the file descriptor ?
What file or device should the file descriptor refer to ?
If we are talking about the harddrive then should it refer to /dev/sda ?
Please share your ideas.
