NAME
addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr, mvwaddstr,
mvwaddnstr - add a string of characters to a curses window and advance
cursor
SYNOPSIS
#include <ncurses/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 char-
acters. 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 charac-
ters, or until a terminating null is reached. If n is -1, then the en-
tire 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 re-
turns 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.
NOTES
All of these functions except waddnstr may be macros.
PORTABILITY
These functions are described in the XSI Curses standard, Issue 4.
