  *              If terminal zero is present, then the specified expression is meaningless.

  * @name Access Of Memory Location After The End Of A Buffer Using Strncat
  * @description Calls of the form `strncat(dest, source, sizeof (dest) - strlen (dest))` set the third argument to one more than possible. So when `dest` is full, the expression `sizeof(dest) - strlen (dest)` will be equal to one, and not zero as the programmer might think. Making a call of this type may result in a zero byte being written just outside the `dest` buffer.
