What we found amazing was how the flow of control was transferred between subroutines. Careful inspection will show that the array of pointers to functions named ‘vi’ refers to functions which seem to not be directly called. Even so, these pointers to functions are being used as an argument to signal. Can you determine why this is being done and how it is being exploited?
Some compilers complained about this file, so we changed: ‘=++I’ to ‘= ++I’.
