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

Syntax

cc ... -lcurses

#include <curses.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 of elements that fit on the line.

The window cursor is not advanced. These routines work faster than waddnstr(S-osr5) because they merely copy chstr into the window image structure. On the other hand, you must be careful when using these functions because:

They don't do any kind of checking (such as for the newline character).
They don't advance the current cursor position.
They truncate the string, rather than wrapping it around to the new line.

Return values

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

Warning

The header file curses.h automatically includes the header files stdio.h and unctrl.h.

The following routines can be macros:

: addchstr(S-osr5)
: addchnstr(S-osr5)
: waddchstr(S-osr5)
: mvaddchstr(S-osr5)
: mvaddchnstr(S-osr5)
: mvwaddchstr(S-osr5)
: mvwaddchnstr(S-osr5)
