70 <STRONG>waddwstr</STRONG> writes the characters of the (wide-null-terminated) wide-
71 character string <EM>wstr</EM> to the window <EM>win</EM>. Its process is similar to
72 constructing a <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM> for each <EM>wchar</EM><STRONG>_</STRONG><EM>t</EM> in <EM>wstr</EM>, then calling
73 <STRONG><A HREF="curs_add_wch.3x.html">wadd_wch(3x)</A></STRONG> with the resulting <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>.
75 <STRONG>o</STRONG> Spacing and non-spacing characters in the string are processed one
78 <STRONG>o</STRONG> control characters are processed as in <STRONG><A HREF="curs_add_wch.3x.html">wadd_wch(3x)</A></STRONG>.
80 <STRONG>waddnwstr</STRONG> writes at most <EM>n</EM> wide characters, or until a terminating wide
81 null character occurs in <EM>wstr</EM>. If <EM>n</EM> is -1, <STRONG>waddnwstr</STRONG> writes the entire

88 These functions return <STRONG>OK</STRONG> on success and <STRONG>ERR</STRONG> on failure.
90 X/Open Curses does not specify any error conditions. <EM>ncurses</EM> returns
93 <STRONG>o</STRONG> if the window pointer is <STRONG>NULL</STRONG>,
95 <STRONG>o</STRONG> if the string pointer is <STRONG>NULL</STRONG>, or
97 <STRONG>o</STRONG> if an internal <STRONG><A HREF="curs_add_wch.3x.html">wadd_wch(3x)</A></STRONG> call returns an error.
99 Functions with a "mv" prefix first perform cursor movement using
100 <STRONG><A HREF="curs_move.3x.html">wmove(3x)</A></STRONG> and fail if the position is outside the window, or (for "mvw"
101 functions) if the <EM>WINDOW</EM> pointer is null.

105 All of these functions except <STRONG>waddnwstr</STRONG> may be implemented as macros.
