NAME

addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr, mvwaddstr, mvwaddnstr - add a string of characters to a curses window and advance 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 character 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 characters, 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

*
if the window pointer is null or
*
if the string pointer is null or
*
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.
