addstr(3NCURSES)addstr(3NCURSES)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 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 entire
string will be added, up to the maximum number of characters that will
fit on the line, or until a terminating null is reached.
RETURN VALUE
All routines return the integer ERR upon failure and OK on success (the
SVr4 manuals specify only "an integer value other than ERR") upon suc‐
cessful completion.
X/Open does not define any error conditions. This implementation re‐
turns 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.
NOTES
Note that all of these routines except waddstr and waddnstr may be
macros.
PORTABILITY
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.
