NAME

       addch, mvaddch, mvwaddch, waddch - add a character (with rendition) to a window

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 addch(const chtype ch);

       int mvaddch(int y, int x, const chtype ch);

       int mvwaddch(WINDOW *win, int y, int x, const chtype ch);

       int waddch(WINDOW *win, const chtype ch);

DESCRIPTION

       The addch() function writes a character to the stdscr window  at the current cursor position.  The mvaddch() and mvwaddch() functions write
       the character  to the position indicated by the x (column) and y (row) parameters. The mvaddch() function writes the character to the  std-
       scr   window,  while  mvwaddch()  writes  the character to the window specified by win.	The waddch() function is identical to addch(), but
       writes the  character to the window specified by win.

       These functions advance the cursor after writing the character. Characters that do not fit on the end of the current line  are  wrapped	to
       the beginning of the next line unless the current line is the last line of the window and scrolling is disabled.   In that situation, char-
       acters which extend beyond the end of the line are discarded.

       When ch is a backspace, carriage return, newline, or tab, X/Open Curses moves the cursor appropriately. Each tab character moves the cursor
       to  the	next  tab  stop.  By  default,	tab stops occur every eight columns. When ch is a control character other than backspace, carriage
       return,	newline, or tab, it is written using ^x notation, where x  is a printable character.  When X/Open Curses writes  ch  to  the  last
       character position on a line, it automatically generates a newline. When ch is written to the last character position of a scrolling region
       and scrollok() is enabled, X/Open Curses scrolls the scrolling region  up one line (see clearok(3XCURSES)).

PARAMETERS

       wchstr	 Is a pointer to the cchar_t string to be copied to the window.

       n	 Is the maximum number of characters to be copied from wchstr.	 If n is less than 0, the entire string is written or as  much	of
		 it as fits on the line.

       y	 Is the y (row) coordinate of the starting position of wchstr in the window.

       x	 Is the x (column) coordinate of the starting position of wchstr  in the window.

       win	 Is a pointer to the window to which the string is to be copied.

RETURN VALUES

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

ERRORS

       None.
