- These functions copy the (null-terminated) <I>chstr</I> array 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.
+ <STRONG>waddchstr</STRONG> copies the string of <EM>curses</EM> characters <EM>chstr</EM> to the window
+ <EM>win</EM>. A null <EM>curses</EM> character terminates the string. <STRONG>waddchnstr</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.
- The window cursor is <I>not</I> advanced. These functions work faster than
- <B>waddnstr</B>. On the other hand:
+ Because these functions do not call <STRONG><A HREF="curs_addch.3x.html">waddch(3x)</A></STRONG> internally, they are
+ faster than <STRONG><A HREF="curs_addstr.3x.html">waddstr(3x)</A></STRONG> and <STRONG><A HREF="curs_addstr.3x.html">waddnstr(3x)</A></STRONG>. On the other hand, they
- <B>o</B> they do not perform checking (such as for the newline, backspace,
- or carriage return characters),
+ <STRONG>o</STRONG> do not treat the backspace, carriage return, or line feed
+ characters specially;
- <B>o</B> they do not advance the current cursor position,
+ <STRONG>o</STRONG> do not represent unprintable characters with <STRONG><A HREF="unctrl.3x.html">unctrl(3x)</A></STRONG>;
- <B>o</B> they do not expand other control characters to ^-escapes, and
+ <STRONG>o</STRONG> do not update the cursor position to follow the last character
+ written;
- <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> 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>chstr</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.
