CURS_GETCH(3CURSES)					   CURS_GETCH(3CURSES)

NAME
       curs_getch,  getch,  wgetch,  mvgetch, mvwgetch, ungetch - get (or push
       back) characters from curses terminal keyboard

SYNOPSIS
       cc [ flag ... ] file ... -lcurses [ library ... ]
       #include <curses.h>

       int getch(void);

       int wgetch(WINDOW *win);

       int mvgetch(int y, int x);

       int mvwgetch(WINDOW *win, int y, int x);

       int ungetch(int ch);

DESCRIPTION
       With the getch(), wgetch(), mvgetch(), and mvwgetch() routines a	 char‐
       acter is read from the terminal associated with the window. In no-delay
       mode, if no input is waiting, the value ERR is returned. In delay mode,
       the  program waits until the system passes text through to the program.
       Depending on the setting of  cbreak(),  this  is	 after	one  character
       (cbreak	mode),	or  after  the first newline (nocbreak mode). In half-
       delay mode, the program waits until a character is typed or the	speci‐
       fied  timeout has been reached. Unless noecho() has been set, the char‐
       acter will also be echoed into the designated window.

       If the window is not a pad, and it has been moved or modified since the
       last call to wrefresh(), wrefresh() will be called before another char‐
       acter is read.

       If keypad() is TRUE, and a function key is pressed, the token for  that
       function	 key is returned instead of the raw characters. Possible func‐
       tion keys are defined in <curses.h> with integers beginning with	 0401,
       whose names begin with KEY_. If a character that could be the beginning
       of a function key (such as escape) is received, curses sets a timer. If
       the  remainder  of  the sequence does not come in within the designated
       time, the character is passed  through;	otherwise,  the	 function  key
       value  is  returned. For this reason, many terminals experience a delay
       between the time a user presses	the  escape  key  and  the  escape  is
       returned	 to  the  program. Since tokens returned by these routines are
       outside the ASCII range, they are not printable.

       The ungetch() routine places  ch	 back  onto  the  input	 queue	to  be
       returned by the next call to wgetch().

   Function Keys
       The  following  function keys, defined in <curses.h>, might be returned
       by getch() if keypad() has been enabled. Note that not all of these may
       be supported on a particular terminal if the terminal does not transmit
       a unique code when the key is pressed or if the definition for the  key
       is not present in the terminfo database.

RETURN VALUES
       All routines return the integer ERR upon failure.  The  ungetch()  rou‐
       tine  returns  an  integer value other than ERR upon successful comple‐
       tion.  The other routines return the next input character  or  function
       key code upon successful completion.

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:

       ┌───────────────┬─────────────────┐
       │ATTRIBUTE TYPE │ ATTRIBUTE VALUE │
       ├───────────────┼─────────────────┤
       │MT-Level       │ Unsafe		 │
       └───────────────┴─────────────────┘

       curses(3CURSES), attributes(5)

NOTES
       The header <curses.h> automatically includes the headers	 <stdio.h> and
       <unctrl.h>.

       Use of the escape key for a single character function is discouraged.

       When  using  getch(), wgetch(), mvgetch(), or mvwgetch(), nocbreak mode
       (nocbreak()) and	 echo mode (echo()) should not be  used	 at  the  same
       time.  Depending	 on the state of the tty driver when each character is
       typed, the program may produce undesirable results.

       Note that getch(), mvgetch(), and mvwgetch() may be macros.
