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

A possible solution with structs:

struct func_wrap
{
    struct func_wrap (*func)(void);
};

struct func_wrap func_test(void)
{
    struct func_wrap self;

    self.func = func_test;
    return self;
}

Compiling with gcc -Wall gave no warnings, but I'm not sure if this is 100% portable.
