In our first part on pointers, we covered the basics and common pitfalls of pointers in C. If we had to break it down into one sentence, the main principle of pointers is that they are simply data ...

The previous two posts (part 1 and part 2) have been exploring the fundamentals of using pointers from the basics of declaring a pointer to the more complex notation of manipulating pointers. An ...

This is an excellent question. Zero-length arrays, also known as flexible arrays, are used to implement variable-length arrays, primarily in structures. That's a little confusing, so let's look at an ...

Pointer arrays are a useful tool for mapping peripheral registers to a driver. There are many advantages to using pointer arrays such as simplified initializations and the ability to generate a ...

One of the fundamental issues in driver design is deciding how to map to the peripheral registers. Over the years there have been many different methods that have been used such as setting up ...
