The addstr() function writes a null-terminated string of multi-byte
characters to the stdscr window at the current cursor position. The
waddstr() function performs an identical action, but writes the
character to the window specified by win. The mvaddstr() and
mvwaddstr() functions write the string to the position indicated by
the x (column) and y (row) parameters (the former to the stdscr
window; the latter to window win).
The addnstr(), waddnstr(), mvaddnstr(), and mvwaddnstr() functions
are similar but write at most n characters to the window. If n is
less than 0, the entire string is written.
All of these functions advance the cursor after writing the string.
These functions are functionally equivalent to calling the
corresponding function from the addch(3XCURSES) set of functions once
for each character in the string. Refer to the curses(3XCURSES) man
page for a complete description of special character handling and of
the interaction between the window rendition (or background character
and rendition) and the character written.
Note that these functions differ from the addchstr() set of functions
in that the addchstr(3XCURSES) functions copy the string as is
(without combining each character with the window rendition or the
background character and rendition.
str
Is a pointer to the character string that is to be written to
the window.
n
Is the maximum number of characters to be copied from str. If
n is less than 0, the entire string is written or as much of
it as fits on the line.
y
Is the y (row) coordinate of the starting position of str in
the window.
x
Is the x (column) coordinate of the starting position of str
in the window.
win
Is a pointer to the window in which the string is to be
written.
On success, these functions return OK. Otherwise, they return ERR.
None.

DESCRIPTION
The addstr() function writes a null-terminated string of multi-byte
characters to the stdscr window at the current cursor position. The
waddstr() function performs an identical action, but writes the
character to the window specified by win. The mvaddstr() and
mvwaddstr() functions write the string to the position indicated by
the x (column) and y (row) parameters (the former to the stdscr
window; the latter to window win).
The addnstr(), waddnstr(), mvaddnstr(), and mvwaddnstr() functions
are similar but write at most n characters to the window. If n is
less than 0, the entire string is written.
All of these functions advance the cursor after writing the string.
These functions are functionally equivalent to calling the
corresponding function from the addch(3XCURSES) set of functions once
for each character in the string. Refer to the curses(3XCURSES) man
page for a complete description of special character handling and of
the interaction between the window rendition (or background character
and rendition) and the character written.
Note that these functions differ from the addchstr() set of functions

the window.
x
Is the x (column) coordinate of the starting position of str
in the window.
win
