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.
