       curs_addwch,   addwch,	waddwch,   mvaddwch,   mvwaddwch,   echowchar,
       wechowchar - add a wchar_t character (with attributes) to a curses win‐
       dow and advance cursor

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


       int addwch(chtype wch);

       int waddwch(WINDOW *win, chtype wch);

       int mvaddwch(int y, int x, chtype wch);

       int mvwaddwch(WINDOW *win, int y, int x, chtype wch);

       int echowchar(chtype wch);

       int wechowchar(WINDOW *win, chtype wch);

       The   addwch(),waddwch(),mvaddwch(),  and  mvwaddwch() routines put the
       character  wch, holding a wchar_t character, into  the  window  at  the
       current	cursor	position of the window and advance the position of the
       window cursor. Their function is similar to that of putwchar(3C) in the
       C  multibyte library. At the right margin, an automatic newline is per‐
       formed. At the bottom of the scrolling region, if scrollok is  enabled,
       the scrolling region is scrolled up one line.

       If   wch is a tab, newline, or backspace, the cursor is moved appropri‐
       ately within the window.	 A  newline  also  does	 a   clrtoeol(3CURSES)
       before  moving.	Tabs  are  considered to be at every eighth column. If
       wch is another control character, it  is	 drawn	in  the	 ^X  notation.
       Calling	 winwch(3CURSES)  after	 adding	 a  control character does not
       return the control character, but instead returns the representation of
       the control character.

       Video  attributes  can  be combined with a  wchar_t character by OR-ing
       them into the parameter. This results in these  attributes  also	 being
       set. (The intent here is that text, including attributes, can be copied
       from one place to another using	inwch()	 and   addwch().)  See	stand‐
       out(3CURSES), predefined video attribute constants.

       The   echowchar() and wechowchar() routines are functionally equivalent
       to a call to  addwch() followed by a call  to  refresh(3CURSES),	 or  a
       call  to	 waddwch() followed by a call to wrefresh(3CURSES). The knowl‐
       edge that only a single character is being output is taken into consid‐
       eration	and,  for  non-control	characters, a considerable performance
       gain might be seen by using these routines  instead  of	their  equiva‐

   Line Graphics
       The  following  variables may be used to add line drawing characters to
       the screen with routines of the	addwch() family.  When	variables  are
       defined	for  the  terminal,  the  A_ALTCHARSET	bit is turned on. (See
       curs_attr(3CURSES)). Otherwise, the default character listed  below  is
       stored  in the variable. The names chosen are consistent with the VT100

       All routines return the integer ERR upon failure and an	integer	 value
       other  than  ERR	 upon successful completion, unless otherwise noted in
       the preceding routine descriptions.

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

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

       Note  that   addwch(),  mvaddwch(), mvwaddwch(), and echowchar() may be

       None of these routines can use the color attribute in chtype.
