A critical tool when developing an embedded system in C is an understanding of how pointers work. Misunderstanding pointer fundamentals can result in long hours spent debugging a system or a hidden ...

Pointers — you either love them, or you haven’t fully understood them yet. But before you storm off to the comment section now, pointers are indeed a polarizing subject and are both C&#… ...

This may fall under the heading of "Don't do that" but did cause me to be slightly curious.What would happen if you say, created a pointer to a function that took three ints as arguments, but then ...

First off, I'll have coded a workaround before you read this. But now I've got a bee up my bu, errr, bonnett.I'm writing test code in C, and I need 100 pointers to (unique) functions. I'm trying ...

One of the most common applications for using function pointers is in task schedulers. Every embedded system contains some type of task scheduler whether it is a simple round robin loop or a state of ...

The C language allows you to provide a pointer to a function, just like a pointer to a variable. In both cases, a C pointer contains the address and the type information about the entity being pointed ...

So read on! Function Pointers In general, function pointers aren’t any more mysterious than data pointers: the main difference is that one references variables and the other references functions.

Pointers are a powerful feature in C and C++, but they come with risks that can lead to serious issues like NULL pointer crashes. By following these best practices—initializing pointers, checking for ...
