curs_addchstr: addchstr, addchnstr, waddchstr, waddchnstr, mvaddchstr, mvaddchnstr, mvwaddchstr, mvwaddchnstr -- add string of characters (and attributes) to a curses window

Synopsis

cc [flag . . .] file -locurses [library . . .]

#include <ocurses.h>

int addchstr(chtype chstr);
int addchnstr(chtype chstr, int n);
int waddchstr(WINDOW win, chtype chstr);
int waddchnstr(WINDOW win, chtype chstr, int n);
int mvaddchstr(int y, int x, chtype chstr);
int mvaddchnstr(int y, int x, chtype chstr, int n);
int mvwaddchstr(WINDOW win, int y, int x, chtype chstr);
int mvwaddchnstr(WINDOW win, int y, int x, chtype chstr, int n);

Description

All of these routines copy chstr directly into the window image structure starting at the current cursor position. The four routines with n as the last argument copy at most n elements, but no more than will fit on the line. If n=-1 then the whole string is copied, to the maximum number that fit on the line.

The position of the window cursor is not advanced. These routines work faster than waddnstr because they merely copy chstr into the window image structure. On the other hand, care must be taken when using these functions because they don't perform any kind of checking (such as for the newline character), they don't advance the current cursor position, and they truncate the string, rather then wrapping it around to the new line.

Return values

All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion, unless otherwise noted in the preceding routine descriptions.

Note that all routines except waddchnstr may be macros.
