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 ...

And being pointers, we can pretty much treat them like any other pointer. Passing Registers to Functions To a pointer, it doesn’t matter what kind of memory it is pointing to.

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.

I'm trying to cast my function to an int, add an offset, and cast it back to a function pointer (I don't plan on calling the pointers).

IIRC C++ does not allow methods to be passed as function pointers. if b () were outside a class (a global function) it could be passed safely. Static methods might also be callable, but I'm not sure.

When using function pointers, though, it is always a good idea to first verify that the referenced location in memory is not NULL and does exist within the system. Function pointers can be very ...

VTABLE and Pointers to Functions in C Even though it’s called a “table,” the VTABLE isn’t typically implemented in C as an array but rather as a struct of pointers to the virtual functions, such as ...

A callback is a function that is executed through a pointer where the function being pointed to contains application specific code. Callbacks are normally passed into a function and provides the ...
