FBB::OneKey - Single keystroke input, not requiring `Return’
#include <bobcat/onekey>
Linking option: -lbobcat
OneKey objects may be used to realize `direct keyboard input’: a pressed key becomes available without the need for pressing Enter. The characters are obtained from the standard input stream. Direct key entry remains in effect for as long as the OneKey object exists. Once the object is destroyed the standard input stream will return to its default mode of operation, in which input is `confirmed’ by a newline character.

All constructors, members, operators and manipulators, mentioned in this

-
The OneKey::Mode enumeration is used to control echoing of returned characters. It has two values:
Copy and move constructors (and assignment operators) are not available.
