Question

What does this do?

int *(*pfp) ();

Answer 1

int *(*pfp) ();

Creates a pointer to a function that returns int*. The function pointer name ispfp.

Here’s an example:

int* myFunc(void)
{
   return NULL;
}


int main(int argc, char**argv)
{
  int *(*pfp) (void);
  pfp = myFunc;
  return 0;
}

Note: Since the parameters of the function pointer is not (void) that you gave, that means that the parameter list is not specified in C. In C++ it would mean that it’s a function with no parameters exactly.
