- add an array of complex characters (and attributes) to a
curses window
</PRE>
<H2>DESCRIPTION</H2><PRE>
- These routines copy the array of complex characters <EM>wchstr</EM>
- into the window image structure at and after the current
- cursor position. The four routines with <EM>n</EM> as the last
- argument 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 routines work
- faster than <STRONG>waddnstr</STRONG>. On the other hand, they do not per-
- form checking (such as for the newline, backspace, or car-
- riage return characters), they do not advance the current
- cursor position, they do not expand other control charac-
- ters to ^-escapes, and they truncate the string if it
- crosses the right margin, rather then wrapping it around
- to the new line.
-
- These routines end successfully on encountering a null
- <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>, 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.
+ These functions copy the (null-terminated) array of com-
+ plex characters <EM>wchstr</EM> into the window image structure
+ starting at the current cursor position. The four func-
+ tions with <EM>n</EM> as the last argument 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:

- All routines return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on

+<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.
+ 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.

+ All functions except <STRONG>wadd_wchnstr</STRONG> may be macros.
