67 <H2>DESCRIPTION</H2><PRE>
68        These routines copy the array of complex characters <EM>wchstr</EM>
69        into  the  window image structure at and after the current
70        cursor position.  The four routines with  <EM>n</EM>  as  the  last
71        argument  copy  at  most <EM>n</EM> elements, but no more than will
72        fit on the line.  If <STRONG>n</STRONG>=<STRONG>-1</STRONG> then the whole array is  copied,
73        to  the  maximum number of characters that will fit on the
74        line.
75
76        The window cursor is <EM>not</EM> advanced.   These  routines  work
77        faster than <STRONG>waddnstr</STRONG>.  On the other hand, they do not per-
78        form checking (such as for the newline, backspace, or car-
79        riage  return characters), they do not advance the current
80        cursor position, they do not expand other control  charac-
81        ters  to  ^-escapes,  and  they  truncate the string if it
82        crosses the right margin, rather then wrapping  it  around
83        to the new line.
84
85        These  routines  end  successfully  on encountering a null
86        <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>, or when they have filled the current line.  If  a
87        complex  character cannot completely fit at the end of the
88        current line, the remaining columns are  filled  with  the
89        background character and rendition.

93 <H2>NOTES</H2><PRE>
94        All functions except <STRONG>wadd_wchnstr</STRONG> may be macros.

98 <H2>RETURN VALUES</H2><PRE>
99        All routines return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on
100        success.
