- .De
- Set or unset the terminal to/from cbreak mode.
- The misnamed macros
- .Fn crmode
- and
- .Fn nocrmode
- are retained for backwards compatibility
- with ealier versions of the library.

- .Fd noecho "" \*m
- .De
- Sets the terminal to echo or not echo characters.

- .Fd getch "" \*m
- .Fd wgetch win
- WINDOW *win;
- .De
- Gets a character from the terminal and (if necessary)
- echos it on the window.
- \*(Es
- Otherwise, the character gotten is returned.
- If
- .i noecho
- has been set, then the window is left unaltered.
- In order to retain control of the terminal,
- it is necessary to have one of
- .i noecho ,
- .i cbreak ,
- or
- .i rawmode
- set.
- If you do not set one,
- whatever routine you call to read characters will set
- .i cbreak
- for you,
- and then reset to the original mode when finished.

- .Fd getstr str \*m
- char *str;
- .Fd wgetstr win\*,str
- WINDOW *win;
- char *str;
- .De
- Get a string through the window
- and put it in the location pointed to by
- .Vn str ,
- which is assumed to be large enough to handle it.
- It sets tty modes if necessary,
- and then calls
- .Fn getch
- (or
- .Fn wgetch ) "" win
- to get the characters needed to fill in the string
- until a newline or EOF is encountered.
- The newline stripped off the string.
- \*(Es

- .Fd \*_putchar c
- char c;
- .De
- Put out a character using the
- .Fn putchar
- macro.
- This function is used to output every character
- that
- .b curses
- generates.
- Thus,
- it can be redefined by the user who wants to do non-standard things
- with the output.
- It is named with an initial \*(lq\*_\*(rq
- because it usually should be invisible to the programmer.
- .Ds
- .Fd raw "" \*m
- .Fd noraw "" \*m
- .De
- Set or unset the terminal to/from raw mode.
