Controlling Hardware with ioctls
Once you learn the ioctl system call, you'll be able to check the status of the Ethernet link light and other miscellaneous but important facts about hardware.

A few years ago, I had a laptop that I used at work and at home. To simplify my network configuration and not have to change it manually depending on where I was, I decided to use DHCP in both places. It was the standard at work, so I implemented a DHCP server at home. This worked well except when I booted the system without it being plugged in to either network. When I did, the laptop spent a lot of time trying to find a DHCP server without success before continuing the rest of the startup process.

I concluded that an ideal solution to this lag time would be for the system to start with the Ethernet interface down and have it come up if, and only if, the cable was connected to a hub, that is, if I had a link light on the Ethernet interface. The best way to do this appeared to be having a shell script call a program whose return code would indicate whether a link had been established on a particular network interface. So began my quest for a method to determine this link status of my 10/100Base-T interface.

Not having done much low-level Linux programming, it took me a bit of time to discover that most of this type of interaction with device drivers usually is done through the ioctl library call (an abbreviation of I/O control), prototyped in sys/ioctl.h:
