67        These routines return a string of  <STRONG>wchar_t</STRONG>  wide  characters  in  <EM>wstr</EM>,
68        extracted starting at the current cursor position in the named window.
69
70        The  four  functions  with <EM>n</EM> as the last argument return a leading sub-
71        string at most <EM>n</EM> characters  long  (exclusive  of  the  trailing  NUL).
72        Transfer  stops  at  the  end of the current line, or when <EM>n</EM> characters
73        have been stored at the location referenced by <EM>wstr</EM>.
74
75        If the size <EM>n</EM> is not large enough to store a complete  complex  charac-
76        ter, an error is generated.

80        All routines except <STRONG>winnwstr</STRONG> may be macros.
81
82        Each cell in the window holds a complex character (i.e., base- and com-
83        bining-characters) together with attributes and color.  These functions
84        store  only  the  wide  characters, ignoring attributes and color.  Use
85        <STRONG>in_wchstr</STRONG> to return the complex characters from a window.
86
87
88 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
89        All routines return <STRONG>ERR</STRONG> upon failure.  Upon successful completion,  the
90        *<STRONG>inwstr</STRONG> routines return <STRONG>OK</STRONG>, and the *<STRONG>innwstr</STRONG> routines return the number
91        of characters read into the string.
92
93        Functions with a "mv" prefix first  perform  a  cursor  movement  using
94        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
95        the window pointer is null.
