  71 <H2>DESCRIPTION</H2><PRE>
  72        These routines return a NULL-terminated  array  of  <STRONG>chtype</STRONG>
  73        quantities, starting at the current cursor position in the
  74        named window and ending at the right margin of the window.
  75        The  four  functions with <EM>n</EM> as the last argument, return a
  76        leading substring at most <EM>n</EM> characters long (exclusive  of
  77        the  trailing (chtype)0).  Constants defined in <STRONG>&lt;curses.h&gt;</STRONG>
  78        can be used with the <STRONG>&amp;</STRONG> (logical AND) operator  to  extract
  79        the  character or the attribute alone from any position in
  80        the <EM>chstr</EM> [see <STRONG><A HREF="curs_inch.3x.html">curs_inch(3x)</A></STRONG>].
  81
  82
  83 </PRE>
  84 <H2>RETURN VALUE</H2><PRE>
  85        All routines return the integer <STRONG>ERR</STRONG> upon  failure  and  an
  86        integer  value  other  than <STRONG>ERR</STRONG> upon successful completion
  87        (the number of  characters  retrieved,  exclusive  of  the
  88        trailing 0).
  89
  90        No  error  conditions are defined.  If the <EM>chstr</EM> parameter
  91        is null, no data is returned, and the return value is  ze-
  92        ro.
  93
  94        Functions  with a "mv" prefix first perform a cursor move-
  95        ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
  96        outside the window, or if the window pointer is null.
  97
  98
  99 </PRE>
 100 <H2>NOTES</H2><PRE>
 101        Note  that  all  routines  except <STRONG>winchnstr</STRONG> may be macros.
 102        SVr4 does not document whether the result string is  zero-
 103        terminated;  it  does  not document whether a length limit
 104        argument includes any trailing 0; and it does not document
 105        the meaning of the return value.
 106
 107
 108 </PRE>
 109 <H2>PORTABILITY</H2><PRE>
 110        These  functions are described in the XSI Curses standard,
 111        Issue 4.  It is no more specific than the SVr4  documenta-
 112        tion on the trailing 0.  It does specify that the success-
 113        ful return of the functions is <STRONG>OK</STRONG>.
