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 advanced  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 implementation
   returns an error

   ·   if the window pointer is null or

   ·   if the string pointer is null or

   ·   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.

NOTES

   All of these functions except waddnstr may be macros.

PORTABILITY

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