Who needs functional programming...

... when C has function pointers?

Shouldn't this work fine?
struct fp
{
struct fp *(*func)(void *);
};

C doesn't even have a generic function pointer type on all implementations

I fail to see how a generic function pointer would be of use, but you can always return a void * that you then cast into a pointer to a struct that contains the function pointer you want.

In the end it's just easier to use

void* (*fp)(...);

and cast the return value.

void (*)()
// or anything really
any function pointer can be cast to any other function pointer and back again, and it shall be equal to the original pointer.

That's cause C is untyped. Not unityped like Phython or Rabbi or Scheme, but untyped like fucking assembly.

§ 6.3.2.3
``A pointer to a function of one type may be converted to a pointer to a function of another type and back again; the result shall compare equal to the original pointer.´´
