GClasses::GPassiveConsole Class Reference

Detailed Description

This class provides a non-blocking method for reading characters from stdin. (If there are no characters ready in stdin, it immediately returns '\0'.) The constructor sets flags on the console so that it passes characters to the stream immediately (instead of when Enter is pressed), and so that it doesn't echo the keys (if desired), and it makes stdin non-blocking. The destructor puts all those things back the way they were.
