NAME
\%addwstr, \%addnwstr, \%waddwstr, \%waddnwstr, \%mvaddwstr, \%mvaddnwstr, \%mvwaddwstr, \%mvwaddnwstr - add a wide-character string to a curses window and advance the cursor
SYNOPSIS
#include <curses.h>

int addwstr(const wchar_t *wstr); int mvaddwstr(int y, int x, const wchar_t *wstr); int mvwaddwstr(WINDOW *win, int y, int x, const wchar_t *wstr); int waddwstr(WINDOW *win, const wchar_t *wstr);

int addnwstr(const wchar_t *wstr, int n); int mvaddnwstr(int y, int x, const wchar_t *wstr, int n); int mvwaddnwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n); int waddnwstr(WINDOW *win, const wchar_t *wstr, int n);

DESCRIPTION
waddwstr writes the characters of the (wide-null-terminated) wide-character string wstr to the window win . Its process is similar to constructing a cchar_t for each wchar_t in wstr , then calling \%wadd_wch(3X) with the resulting cchar_t . .bP Spacing and non-spacing characters in the string are processed one at a time, and .bP control characters are processed as in \%wadd_wch(3X).

waddnwstr writes at most n wide characters, or until a terminating wide null character occurs in wstr . If n is -1, waddnwstr writes the entire wide string.

\%ncurses(3X) describes the variants of these functions.

RETURN VALUE
These functions return OK on success and ERR on failure.

X/Open Curses does not specify any error conditions. \%ncurses returns an error .bP if the window pointer is NULL , .bP if the string pointer is NULL , or .bP if an internal \%wadd_wch(3X) call returns an error.

Functions prefixed with \*(``mv\*('' first perform cursor movement and fail if the position ( y , x ) is outside the window boundaries.

NOTES
All of these functions except waddnwstr may be implemented as macros.
PORTABILITY
X/Open Curses, Issue 4 describes these functions.
SEE ALSO
\%curs_addstr(3X) describes comparable functions of the \%ncurses library in its non-wide-character configuration.
