NAME

       curs_addch, addch, waddch, mvaddch, mvwaddch, echochar, wechochar - add a character (with attributes) to a curses window and advance cursor

SYNOPSIS

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

       int addch(chtype ch);

       int waddch(WINDOW *win, chtype ch);

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

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

       int echochar(chtype ch);

       int wechochar(WINDOW *win, chtype ch);

DESCRIPTION

       With  the  addch(), waddch(), mvaddch(), and mvwaddch() routines, the character ch is put into the window at the current cursor position of
       the window and the position of the window cursor is advanced. Its function is similar to that of putchar(). At the right margin,  an  auto-
       matic newline is performed. At the bottom of the scrolling region, if scrollok() is enabled, the scrolling region is scrolled up one line.

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

       Video attributes can be combined with a 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 inch() and addch().) (see standout(), prede-
       fined video attribute constants, on the curs_attr(3CURSES) page).

       The echochar() and wechochar() routines are functionally equivalent to a call to addch() followed by a call to refresh(), or a call to wad-
       dch  followed by a call to wrefresh(). The knowledge that only a single character is being output is taken into consideration and, for non-
       control characters, a considerable performance gain might be seen by using these routines instead of their equivalents.

   Line Graphics
       The following variables may be used to add line drawing characters to the screen with routines of the addch() 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 nomenclature.
