curs_addstr 3x 2023-11-18 ncurses 6.4 Library calls

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


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


       #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);


       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.


       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.


       All of these functions except waddnstr may be macros.


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