Description:
addch() adds the chtype ch to the default window (stdscr) at the
current cursor position, and advances the cursor. Note that
chtypes can convey both text (a single character) and
attributes, including a color pair. add_wch() is the wide-
character version of this function, taking a pointer to a
cchar_t instead of a chtype.
waddch() is like addch(), but also lets you specify the window.
(This is in fact the core output routine.) wadd_wch() is the
wide version.
mvaddch() moves the cursor to the specified (y, x) position, and
adds ch to stdscr. mvadd_wch() is the wide version.

If ch is a tab, newline, or backspace, the cursor will be moved
appropriately within the window. If ch is a newline, the
clrtoeol routine is called before the cursor is moved to the
beginning of the next line. If newline mapping is off, the
cursor will be moved to the next line, but the x coordinate will
be unchanged. If ch is a tab the cursor is moved to the next
tab position within the window. If ch is another control
character, it will be drawn in the ^X notation. Calling the

from one place to another by using inch() and addch().
Note that in PDCurses, for now, a cchar_t and a chtype are the
same. The text field is 16 bits wide, and is treated as Unicode
(UCS-2) when PDCurses is built with wide-character support
(define PDC_WIDE). So, in functions that take a chtype, like
addch(), both the wide and narrow versions will handle Unicode.
But for portability, you should use the wide functions.
