curs_addstr(3x)                  Library calls                 curs_addstr(3x)


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


       #include <curses.h>

       int addstr(const char *str);
       int mvaddstr(int y, int x, const char *str);
       int mvwaddstr(WINDOW *win, int y, int x, const char *str);
       int waddstr(WINDOW *win, const char *str);

       int addnstr(const char *str, int n);
       int mvaddnstr(int y, int x, const char *str, int n);
       int mvwaddnstr(WINDOW *win, int y, int x, const char *str, int n);
       int waddnstr(WINDOW *win, const char *str, int n);


       waddstr writes the characters of the (null-terminated)  string  str  to
       the  window win.  Its process is similar to calling waddch(3x) for each
       char in str.  Control characters are processed as in waddch(3x).

       waddnstr writes at most n  characters,  or  until  a  terminating  null
       character  occurs  in  str.   If  n  is  -1, waddnstr writes the entire

       ncurses(3x) describes the variants of these functions.


       These functions return OK on success and ERR on failure.

       In ncurses, they return ERR if

       o   win is NULL,

       o   str is NULL, or

       o   an internal waddch(3x) call returns ERR.

       Functions prefixed with "mv" first perform cursor movement and fail  if
       the position (y, x) is outside the window boundaries.


       All of these functions except waddnstr may be macros.


       X/Open  Curses,  Issue  4  describes  these functions.  It specifies no
       error conditions for them.


       4BSD (1980) curses introduced waddstr  along  with  its  variants,  the
       latter defined as macros.

       SVr3.1 (1987) added waddnstr (and its variants) redefining waddstr as a
       macro wrapping it.


       curs_addwstr(3x) describes comparable functions of the ncurses  library
       in its wide-character configuration (ncursesw).
