NAME

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