Description |
|
The cbreak() and nocbreak() routines enable and disable character-mode operation, respectively. When enabled, characters typed by the user are immediately processed by the program. When disabled, the terminal driver is placed into line canonical input mode, which buffers typed characters (until a newline or carriage return are typed) and handles erase() and kill() character processing. These routines do not affect flow control or interrupt characters.
The terminal may or may not be in character mode
operation initially. Most interactive programs
require cbreak() to be enabled.
