int addnwstr(const wchar_t *wstr, int n);

int addwstr(const wchar_t *wstr);

int mvaddnwstr(int y, int x, const wchar_t *wstr, int n);

int mvaddwstr(int y, int x, const wchar_t *wstr);

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

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

int waddnwstr(WINDOW*win, const wchar_t *wstr, int n);

int waddwstr(WINDOW*win, const wchar_t *wstr);  

DESCRIPTION

The addwstr() function writes a null-terminated wide-character string to the stdscr window at the current cursor position. The waddwstr() function performs an identical action, but writes the string to the window specified by win. The mvaddwstr() and mvwaddwstr() functions write the string to the position indicated by the x (column) and y (row) parameters (the former to the stdscr window; the latter to window win).

The addnwstr(), waddnwstr(), mvaddnwstr(), and mvwaddnwstr() functions write at most n characters to the window. If n is less than 0, the entire string is written. The former two functions place the characters at the current cursor position; the latter two commands use the position specified by the x and y parameters.

All of these functions advance the cursor after writing the string.

These functions are functionally equivalent to building a cchar_t from the wchar_t and the window rendition (or background character and rendition) and calling the wadd_wch(3XCURSES) function once for each wchar_t in the string. Refer to the curses(3XCURSES) man page for a complete description of special character handling and of the interaction between the window rendition (or background character and rendition) and the character written.

Note that these functions differ from the add_wchnstr(3XCURSES) set of functions in that the latter copy the string as is (without combining each character with the foreground and background attributes of the window).  

PARAMETERS

wstr Is a pointer to the wide-character string that is to be written to the window.

n Is the maximum number of characters to be copied from wstr. If n is less than 0, the entire string is written or as much of it as fits on the line.

y Is the y (row) coordinate of the starting position of wstr in the window.

x Is the x (column) coordinate of the starting position of wstr in the window.

win Is a pointer to the window in which the string is to be written.

 

RETURN VALUES

On success, these functions return OK. Otherwise, they return ERR.  

ERRORS

None.
