Function Returning Itself

Question

Is it possible to declare some function type func_t which returns that type, func_t?

In other words, is it possible for a function to retur

Answer 1

No, you cannot declare recursive function types in C. Except inside a structure (or an union), it's not possible to declare a recursive type in C.

Now for the void * solution, void * is only guaranteed to hold pointers to objects and not pointers to functions. Being able to convert function pointers and void * is available only as an extension.
