Passing a pointer to a function?

I want to achieve this code:

state(state);

So, first I declare a pointer to a function. I set the pointer to the start function. And the start function takes a pointer to a function also. I call the function using the state pointer, and pass the state pointer along for modification in start.

How do I properly declare the function pointer created in main, and how do I declare the prototypes?

Solution

  • Your intention isn't very clear but you can pass function pointers like this:

    int g ((*myfunc)(int x))
{
 stuff for g;
 (*myfunc)(2);
}

int f (int a)
{
 stuff for f;
}

main()
{
 g (f);
}
