cbreak(3XCURSES)        X/Open Curses Library Functions       cbreak(3XCURSES)

NAME
       cbreak, nocbreak, noraw, raw - set input mode controls

SYNOPSIS
       cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
       -R /usr/xpg4/lib -lcurses [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int cbreak(void);


       int nocbreak(void);


       int noraw(void);


       int raw(void);

DESCRIPTION
       The  cbreak() function enables the character input mode. This overrides
       any previous call to the raw() function and turns the stty flag  ICANON
       off.


       The nocbreak() function sets the line canonical mode and turns the stty
       flag ICANON on without touching the ISIG or IXON flags.


       The  noraw()  function  sets the line canonical mode and turns the stty
       flags ICANON, ISIG, and IXON all on.


       The raw() function sets the character input mode  and  turns  the  stty
       flags  ICANON,  ISIG, and IXON all off. This mode provides maximum con‐
       trol over input.


       It is important to remember that the terminal may  or  may  not  be  in
       character  mode  operation initially. Most interactive programs require
       cbreak() to be enabled.

RETURN VALUES
       On success, these functions return OK. Otherwise, they return ERR.

ERRORS
       None.
