       addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr, mvwaddstr,
       mvwaddnstr - add a string of characters to a curses window and advance


       #include <curses.h>

       int addstr(const char *str);
       int addnstr(const char *str, int n);
       int waddstr(WINDOW *win, const char *str);
       int waddnstr(WINDOW *win, const char *str, int n);

       int mvaddstr(int y, int x, const char *str);
       int mvaddnstr(int y, int x, const char *str, int n);

       These functions write the (null-terminated) character string str on the
       given window.  It is similar to calling waddch once for  each  byte  in
       the string.

       The mv functions perform cursor movement once, before writing any char-
       acters.  Thereafter, the cursor is advanced as a side-effect of writing
       to the window.

       The  four  functions with n as the last argument write at most n bytes,
       or until a terminating null is reached.  If n is -1,  then  the  entire
       string will be added.


       All functions return the integer ERR upon failure and OK on success.

       X/Open  does  not define any error conditions.  This implementation re-
       turns an error

       o   if the window pointer is null or

       o   if the string pointer is null or

       o   if the corresponding calls to waddch return an error.

       Functions with a "mv" prefix first  perform  a  cursor  movement  using
       wmove, and return an error if the position is outside the window, or if
       the window pointer is null.  If an error is returned by the  wmove,  no
       characters are added to the window.

       If  an  error  is  returned  by waddch (e.g., because the window is not
       large enough, or an illegal byte sequence was detected)  only  part  of
       the  string  may be added.  Aside from that, there is a special case in
       waddch where an error may be  returned  after  successfully  writing  a
       character  to  the  lower-right corner of a window when scrollok(3x) is


       All of these functions except waddnstr may be macros.


       These functions are described in the XSI Curses standard, Issue 4.
