How to store various types of function pointers together?

Question

Normal pointers can be stored using a generic void*. e.g.

void* arr[10];
arr[0] = pChar;
arr[1] = pINt;
arr[2] = pA;

Answer 1

You can convert a function pointer to another function pointer of any function type and back without loss.

So as long as when you make the call through the function pointer you typecast it back to the correct type first, you can store all of your function pointers in something like:

typedef void (*fcn_ptr)(void);  // 'generic' function pointer

fcn_ptr arr[10];
