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.
