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.

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 ...

However, in C you have to define a function by name and pass a pointer — not a huge problem, but it can get messy if you have a lot of callback functions that you use only one time.

Function pointers can be used for a wide variety of applications including the implementation of state machines. Just like any tool, it may not always be appropriate to use function pointers for a ...

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 ...
