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 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.   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 disabled.

NOTES

       All of these functions except waddnstr may be macros.

PORTABILITY

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