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 ...

So a function pointer contains the memory address of some code to run, and also must be prototyped the same way as the functions it can point to.

Delegates are type safe function pointers *with an optional this pointer* thus no need to pass one round yourself. Obviously their utility is much enhanced in contract to C++ by virtue of being ...

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.

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.

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 ...

Well yes, but the original calls the fib function pointer, and that now points to the new version. Essentially the original code has been redefined in addition to being wrapped.
