## NAME

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

## SYNOPSIS

           #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);
           int mvwaddstr(WINDOW *win, int y, int x, const char *str);
           int mvwaddnstr(WINDOW *win, int y, int x, const char *str, int n);

## DESCRIPTION

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

           The  mv  functions  perform  cursor  movement once, before
           writing any characters.  Thereafter,  the  cursor  is  ad-
           vanced as a side-effect of writing to the window.

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

## RETURN VALUE

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

           X/Open does not define any error conditions.  This  imple-
           mentation returns 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 move-
           ment using wmove, and return an error if the  position  is
           outside the window, or if the window pointer is null.

## NOTES

           All of these functions except waddnstr may be macros.

## PORTABILITY

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