SYNOPSIS
#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(), mvaddch(), mvwaddch() and
waddch() functions place ch into the current or
specified window at the current or specified position, and then advance the window’s cursor position.
These functions perform wrapping. These functions perform special-character processing.
RETURN VALUE
Upon successful completion, these functions return OK. Otherwise they return ERR.
ERRORS
No errors are defined.
APPLICATION USAGE
These functions are only guaranteed to operate reliably on character sets in which each character fits into
a single byte, whose attributes can be expressed using only constants with the A_ prefix.
