NAME         top

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

SYNOPSIS         top

       #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         top

       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         top

       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.  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 is

NOTES         top

       All of these functions except waddnstr may be macros.

PORTABILITY         top

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