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

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 ...

In the first part of this series, we covered the basics of pointers in C, and went on to more complex arrangements and pointer arithmetic in the second part. Both times, we focused solely on pointers ...

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

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 ...

Pointer Mangling: Glibc protects certain function pointers (like exit handlers) by XORing them with a per-thread secret and rotating the bits. To hijack these pointers, agents must locate the secret ...
