.Sh DESCRIPTION
These functions add character strings and attributes to
.Dv stdscr
or to the specified window.
.Pp
The
.Fn addchstr
function will add the characters and their attributes passed in
.Fa chstr
to
.Dv stdscr
starting at the current cursor position.
Any character attributes set in
.Fa chstr
will be merged with the background attributes currently set on
.Dv stdscr .
The
.Fn waddstr
function does the same as
.Fn addchstr
but adds the string to the window specified by
.Fn win .
.Pp
The
.Fn addchnstr
function will add the contents of
.Fa string
to
.Dv stdscr
but will limit the number of characters added to be, at most,
.Fa n .
If
.Fa n
is \-1 then
.Fa addchnstr
will add the number of characters contained in the null terminated string
.Fa chstr .
Any character attributes set in
.Fa chstr
will be merged with the background attributes currently set on
.Dv stdscr .
.Pp
The
.Fn waddchnstr
function does the same as
.Fa addchnstr
but adds the string to the window specified by
.Fa win .
.Pp
The functions
.Fn mvaddchstr ,
.Fn mwaddchnstr ,
.Fn mvwaddchstr
and
.Fn mvwaddchnstr
are the same as the functions
.Fn addchstr ,
.Fn waddchstr ,
.Fn waddchstr
and
.Fn waddchnstr ,
respectively, except that
.Fn wmove
is called to move the cursor to the position specified by
.Fa y ,
.Fa x
before the string is added to the window.
.Sh RETURN VALUES
The functions will return one of the following values:
.Pp
.Bl -tag -width ERR -compact
.It Er OK
The function completed successfully.
.It Er ERR
