For example, for a microcontroller with multiple GPIO ports a pointer array would be setup to access the direction registers of each of the available ports (Listing 1). Another pointer array would be ...

It is also possible to declare function pointers that return a type or take parameters. For example, below is a function pointer declaration that takes a uint16 as a parameter and then returns a bool.

In my 20 years of C/C++ programming, I’ve had to use a pointer to a function in almost every project. I don’t even recall the circumstances where it would not make a huge un-testable mess ...

All array subscription operations in C get decomposed to pointer arithmetic anyhow; and when dealing with either multi-dimensional arrays or arrays of structs, where you want to access an ...

For example, on my ARM Evaluator-7T single-board computer, the push button, serial ports, and timers can request interrupts, ... The interrupt vector is just a memory-mapped array of pointer_to_ISR at ...

Hi everyone,<BR><BR>I'm continuing on my c coding adventures and I've hit a pointer snag.<BR><BR>I'm basically maintaining a fixed collection of structs that I would like to handle using an array ...

Actually, all I've tried so far is to create a pointer to a single 3D array, and that won't work.<BR><BR>I don't have the code available to me now, which I know is dumb for asking this kind of ...
