    curs_addstr(3x)                  Library calls                 curs_addstr(3x)

## 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

           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 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.
