- These functions copy the (null-terminated) array of complex characters
- <I>wchstr</I> into the window image structure starting at the current cursor
- position. The four functions with <I>n</I> as the last argument copy at most
- <I>n</I> elements, but no more than will fit on the line. If <B>n</B>=<B>-1</B> then the
- whole array is copied, to the maximum number of characters that will
- fit on the line.
-
- The window cursor is <I>not</I> advanced. These functions work faster than
- <B>waddnstr</B>. On the other hand:
+ <STRONG>wadd_wchstr</STRONG> copies the string of complex characters <EM>wchstr</EM> to the
+ window <EM>win</EM>. A null complex character terminates the string. If a
+ complex character does completely fit at the end of the line, <EM>curses</EM>
+ fills the remaining columns with the window background; see <STRONG><A HREF="curs_bkgrnd.3x.html">bkgrnd(3x)</A></STRONG>.
+ <STRONG>wadd_wchnstr</STRONG> does the same, but copies at most <EM>n</EM> characters, or as many
+ as possible if <EM>n</EM> is <STRONG>-1</STRONG>. <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> describes the variants of these
+ functions.
- <B>o</B> they do not perform checking (such as for the newline, backspace,
- or carriage return characters),
+ Because these functions do not call <STRONG><A HREF="curs_add_wch.3x.html">wadd_wch(3x)</A></STRONG> internally, they are
+ faster than <STRONG><A HREF="curs_addwstr.3x.html">waddwstr(3x)</A></STRONG> and <STRONG><A HREF="curs_addwstr.3x.html">waddnwstr(3x)</A></STRONG>. On the other hand, they
- <B>o</B> they do not advance the current cursor position,
+ <STRONG>o</STRONG> do not treat the backspace, carriage return, or line feed
+ characters specially;
- <B>o</B> they do not expand other control characters to ^-escapes, and
+ <STRONG>o</STRONG> do not represent unprintable characters with <STRONG><A HREF="curs_util.3x.html">wunctrl(3x)</A></STRONG>;
- <B>o</B> they truncate the string if it crosses the right margin, rather
- than wrapping it around to the new line.
+ <STRONG>o</STRONG> do not update the cursor position to follow the last character
+ written;
- These functions end successfully on encountering a null <I>cchar</I><B>_</B><I>t</I>, or
- when they have filled the current line. If a complex character cannot
- completely fit at the end of the current line, the remaining columns
- are filled with the background character and rendition.
+ <STRONG>o</STRONG> truncate the string at the window's right margin, rather than
+ wrapping it to the next line and potentially scrolling.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
- All functions return the integer <B>ERR</B> upon failure and <B>OK</B> on success.
+ These functions return <STRONG>OK</STRONG> on success and <STRONG>ERR</STRONG> on failure.
+
+ X/Open Curses does not specify any error conditions. <EM>ncurses</EM> returns
+ <STRONG>ERR</STRONG> if
+
+ <STRONG>o</STRONG> <EM>win</EM> is <STRONG>NULL</STRONG> or
- X/Open does not define any error conditions. This implementation re-
- turns an error if the window pointer is null.
+ <STRONG>o</STRONG> <EM>wchstr</EM> is <STRONG>NULL</STRONG>.
- Functions with a "mv" prefix first perform a cursor movement using
- <B>wmove</B>, and return an error if the position is outside the window, or if
- the window pointer is null.
+ Functions prefixed with "mv" first perform cursor movement and fail if
+ the position (<EM>y</EM>, <EM>x</EM>) is outside the window boundaries.
