-<H2>DESCRIPTION</H2><PRE>
- These functions copy the (null-terminated) <EM>chstr</EM> array in-
- to the window image structure starting at the current cur-
- sor position. The four functions with <EM>n</EM> as the last argu-
- ment copy at most <EM>n</EM> elements, but no more than will fit on
- the line. If <STRONG>n</STRONG>=<STRONG>-1</STRONG> then the whole array is copied, to the
- maximum number of characters that will fit on the line.
- The window cursor is <EM>not</EM> advanced. These functions work
- faster than <STRONG>waddnstr</STRONG>. On the other hand:

+ <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.
- <STRONG>o</STRONG> 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_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
- <STRONG>o</STRONG> they do not advance the current cursor position,
+ <STRONG>o</STRONG> do not treat the backspace, carriage return, or line feed
+ characters specially;
- <STRONG>o</STRONG> they do not expand other control characters to ^-es-
- capes, and
+ <STRONG>o</STRONG> do not represent unprintable characters with <STRONG><A HREF="unctrl.3x.html">unctrl(3x)</A></STRONG>;
- <STRONG>o</STRONG> they truncate the string if it crosses the right mar-
- gin, rather than wrapping it around to the new line.
+ <STRONG>o</STRONG> do not update the cursor position to follow the last character
+ written;
+ <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>RETURN VALUE</H2><PRE>
- All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG>
- on success.
- X/Open does not define any error conditions. This imple-
- mentation returns an error if the window pointer is null.

+ These functions return <STRONG>OK</STRONG> on success and <STRONG>ERR</STRONG> on failure.
- Functions with a "mv" prefix first perform a cursor move-
- ment using <STRONG>wmove</STRONG>, and return an error if the position is
- outside the window, or if the window pointer is null.
+ X/Open Curses does not specify any error conditions. <EM>ncurses</EM> returns
