Info on simple_error() help.

I'm doing a drill that's says to use simple_error(). I'm having a hard time finding infomation on it. What header is simple_error() from? And how do you use it?

simple_error() doesn't exist as far as I've been able to search. I found a reference to it on the creator's website, but it was a personally built one. If you're taking a class, maybe you'll have to look back through your notes or your text book for a reference. Stroustrup's example was as follows:
1
2
3
4
5
6
7
 
// error function to be used (only) until error() is introduced in Chapter 5:
inline void simple_error(string s)	// write ``error: sТТ and exit program
{
	cerr << "error: " << s << '\n';
	keep_window_open();		// for some Windows environments
	exit(1);
}

Thanks. I'm using Stroustrup's book and I must have missed it.
