In windows we create a function in a driver and we can call it from the application using dll as the middle man. What happens in linux? How can we create a custom function (ioctl) for example and call/ use it from the host application?
Any suggestions, insights, examples, links would be great.
this blog post seems to have a nice run-through of writing a device driver in general. ioctl is not specifically mentioned in that post, but the post itself points to the public availability of a book "Linux Device Drivers, 3rd edition", which contains a chapter on ioctl usage as well.
The header files are sufficient for making a driver's function visible to application
