curs_getwch(3X)						       curs_getwch(3X)

     curs_getwch: getwch, wgetwch, mvgetwch, mvwgetwch, ungetwch - get (or
     push back) wchar_t characters from curses terminal keyboard

     #include <curses.h>

     int getwch(void);
     int wgetwch(WINDOW *win);
     int mvgetwch(int y, int x);
     int mvwgetwch(WINDOW *win, int y, int x);
     int ungetwch(int wch);

     The getwch, wgetwch, mvgetwch, and mvwgetwch routines read an EUC
     character from the terminal associated with the window, transform it into
     a wchar_t character, and return a wchar_t character.  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 specified timeout has
     been reached.  Unless noecho has been set, the character 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 character
     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
     function 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.

     The ungetwch routine places wch back onto the input queue to be returned
     by the next call to wgetwch.

   Function Keys
     The following function keys, defined in <curses.h>, might be returned by
     getwch 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.

     The header file <curses.h> automatically includes the header files
     <stdio.h> and <unctrl.h>.

     Use of the escape key by a programmer for a single character function is

     When using getwch, wgetwch, mvgetwch, or mvwgetwch, nocbreak mode and
     echo mode 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 getwch, mvgetwch, and mvwgetwch may be macros.
