-<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 than 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.

+ <STRONG>wadd_wchstr</STRONG> copies the string of complex characters <EM>wchstr</EM> to the

+ 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

+ These were later additions to SVr4.<EM>x</EM>, not appearing in the first SVr4
