*You must know the C programming language to understand this*

typedef void (*ptr)(); // pointer to void function

void HHH(ptr P, ptr I)
{
   P(I);
   return;
}

void DDD(int (*x)())
{
   HHH(x, x);
   return;
}

int main()
{
   HHH(DDD,DDD);
}

In the above Neither DDD nor HHH ever reach their own return
statement thus never halt.

When HHH is a simulating halt decider then HHH sees that
DDD correctly simulated by HHH cannot possibly reach its
own return statement, AKA

    simulating halt decider HHH correctly simulates its input DDD
    until HHH correctly determines that its simulated DDD would never
    stop running unless aborted

*as defined here*

   If simulating halt decider H correctly simulates its input D
   until H correctly determines that its simulated D would never
   stop running unless aborted then

   H can abort its simulation of D and correctly report that D
   specifies a non-halting sequence of configurations.
