CURSES_ADDCH(3)         NetBSD Library Functions Manual        CURSES_ADDCH(3)


NAME

     curses_addch, addch, waddch, mvaddch, mvwaddch -- curses add characters
     to windows routines


LIBRARY

     Curses Library (libcurses, -lcurses)


SYNOPSIS

     #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);


DESCRIPTION

     These functions add characters to stdscr or to the specified window.

     The addch() function adds the character given in ch to stdscr at the cur-
     rent cursor position and advances the current cursor position by one.
     Any character attributes set in ch will be merged with the background
     attributes currently set on stdscr.

     The waddch() function is the same as the addch() function, excepting that
     the character is added to the window specified by win.

     The mvaddch() and mvwaddch() functions are the same as the addch() and
     waddch() functions, respectively, excepting that wmove() is called to
     move the cursor to the position specified by y, x before the character is
     added to the window.


RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.
     The functions that return an int will return one of the following values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.
