- KBHIT.C
*
- Based on the work of W. Richard Stevens in "Advanced Programming in
- the Unix Environment," Addison-Wesley; and of Floyd Davidson.
*
- Contains these functions:
*
- To set the TTY mode:
- tty_set_raw() Unix setup to read a character at a time.
- tty_set_cooked() Unix setup to reverse tty_set_raw()
*
- To read keyboard input:
- kb_getc() keyboard get character, NON-BLOCKING. If a char
- has been typed, return it. Else return 0.
- kb_getc_w() kb get char with wait: BLOCKING. Wait for a char
- to be typed and return it.
*
- How to use:
- tty_set_raw() set the TTY mode to read one char at a time.
- kb_getc() read chars one by one.
- tty_set_cooked() VERY IMPORTANT: restore cooked mode when done.
