curs_addwstr(3X) curs_addwstr(3X)
addwstr, addnwstr, waddwstr, waddnwstr, mvaddwstr, mvaddnwstr,
mvwaddwstr, mvwaddnwstr - add a string of wide characters to a
curses window and advance cursor
#include <curses.h>
int addwstr(const wchar_t *wstr);
int addnwstr(const wchar_t *wstr, int n);
int waddwstr(WINDOW *win, const wchar_t *wstr);
int waddnwstr(WINDOW *win, const wchar_t *wstr, int n);
int mvaddwstr(int y, int x, const wchar_t *wstr);
int mvaddnwstr(int y, int x, const wchar_t *wstr, int n);
int mvwaddwstr(WINDOW *win, int y, int x, const wchar_t *wstr);
int mvwaddnwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n);
These functions write the characters of the (null-terminated)
wchar_t character string wstr on the given window. It is similar
to constructing a cchar_t for each wchar_t in the string, then
calling wadd_wch for the resulting cchar_t.
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
wchar_t characters, or until a terminating null is reached. If n
is -1, then the entire string will be added.
All functions return the integer ERR upon failure and OK on suc‐
cess.
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 wadd_wch return an error.
Functions with a “mv” prefix first perform a cursor movement us‐
ing wmove, and return an error if the position is outside the
window, or if the window pointer is null.
All of these functions except waddnwstr may be macros.
These functions are described in the XSI Curses standard, Issue
4.
