addstr, waddstr, mvaddstr, mvwaddstr - add string to window
int waddstr(win, str)
int mvaddstr(y, x, str)
int y, x;
int mvwaddstr(win, y, x, str)
int y, x;
The routine writes all the characters of the null-terminated character string on the default window at the current (y, x) coordinates.
The routine writes all the characters of the null terminated character string on the specified window at the current (y, x) coordinates.
The routine writes all the characters of the null terminated character string on the default window at the specified (y, x) coordinates.
The routine writes all the characters of the null terminated character string on the specified window at the specified (y, x) coordinates.
The following information applies to all the routines. All the routines return if writing the string causes illegal scrolling. In this
case the routine will write as much as possible of the string on the window.
These routines are functionally equivalent to calling or once for each character in the string.
The routines and are macros.
The and functions return OK on success and ERR on error.

These routines write the characters of the (null-terminated) character string str on the given window. It is similar to calling waddch
once for each character in the string. The four routines with n as the last argument write at most n characters. If n is -1, then the en-
tire string will be added, up to the maximum number of characters that will fit on the line, or until a terminating null is reached.
All routines return the integer ERR upon failure and OK on success (the SVr4 manuals specify only "an integer value other than ERR") upon
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.
Note that all of these routines except waddstr and waddnstr may be macros.
All these entry points are described in the XSI Curses standard, Issue 4. The XSI errors EILSEQ and EOVERFLOW, associated with extended-
level conformance, are not yet detected.

I'm working with an extremely outdated and old system at work. We do not have ncurses, but we do have curses. I need to make a user interface for users connecting with xterm. One issue I've encountered is if the user resizes the window, I'd like to provide functionality to redraw the screen with... (4 Replies)
I'm writing a BBS telnet client, and am trying to implement a status bar into it, at the bottom of the screen.
I am using NCurses to accomplish this. So far, it appears to be working, that is, upon connecting to BBS, it
will display the status bar, and then quickly disappear.
