It causes the output stream to flush when an input request comes along.
That way, you can write
	cout << "Please enter ..."; cin >> ...;
and be sure cout gets flushed before the call to cin>>, so the user 
sees the prompt. 

"The use of this function is discouraged" is Glockenspielspeak for 
"The writer of this documentation doesn't understand it either". :-)
