The program demonstrates the use of pointers to access and manipulate variables. A pointer is a variable that stores the memory address as its value. A pointer variable points to a data type (like int ...

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 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 ...

When writing a program, you'll often want your program to offer different possible behaviors, but it's difficult to anticipate what behaviors users might desire. For example, when writing a sort ...

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 ...

So after a long painful journey tonight of trying to serialize a function pointer, I began to wonder. After seeing the code with a bunch of reinterpret_cast<>() calls, I got to wondering -- how does ...

Embedded programming is a tricky task that looks straightforward to the uninitiated, but those with a few decades of experience know differently. Getting what you want to work predictably or even fit ...

Abstract: Since function pointers are closely related to software control flow and they are writable, attackers often take function pointers as the targets. To protect the function pointers, we ...
