How can I declare a function that can return a pointer to a function of the same type? I'm building a state machine with one function for each state, each of which returns a pointer to the function for the next state. But I can't find a way to declare the functions.
You can't quite do it directly. Either have the function return a generic function pointer, with some judicious casts to adjust the types as the pointers are passed around; or have it return a structure containing only a pointer to a function returning that structure.
