Hardware interaction is pretty general. Today most hardware Interfacing usually is done by the OS and not your C program.

You don't say what hardware you have available.

The first thing I think of is communicating with a serial USB device but do you have any such devices AND do you have the code libraries (SDK) for the devices?

Two basic approaches:

1. Your program interacts directly with the hardware. In this case, you need a Hardware/Software Interface Specification to inform you how the software interacts with that particular piece of hardware.
2. Your program interacts with somebody else's software; and that other software interacts with the hardware. In this case you need a Software Interface Specification to inform you how to use that other software.

Are you perhaps in a hardware class where your job is to design a piece of hardware that can be used by a computer?

Take a look at Wikipedia article on Memory-mapped I/O.
