How to write/pipe to a virtual webcam created by V4L2loopback module?

I have written an application which reads from a webcam and processes the frames using OpenCV on linux.

Now I want to pipe the output of my application to a virtual webcam that has been created by the V4L2loopback module so other applications are able to read it.

I have written the application using C.

How do I approach doing this?

I have found an answer in the old V4L2loopback module's page on Google code.

http://code.google.com/p/v4l2loopback/source/browse/test.c

newer link: https://github.com/umlaeute/v4l2loopback/blob/master/examples/test.c

This has helped me so far just to write to the device.
