<H2>DESCRIPTION</H2><PRE>
These routines return a NULL-terminated array of <STRONG>chtype</STRONG>
quantities, starting at the current cursor position in the
named window and ending at the right margin of the window.
The four functions with <EM>n</EM> as the last argument, return a
leading substring at most <EM>n</EM> characters long (exclusive of
the trailing (chtype)0). Constants defined in <STRONG><curses.h></STRONG>
can be used with the <STRONG>&</STRONG> (logical AND) operator to extract
the character or the attribute alone from any position in
the <EM>chstr</EM> [see <STRONG><A HREF="curs_inch.3x.html">curs_inch(3x)</A></STRONG>].
</PRE>
<H2>RETURN VALUE</H2><PRE>
All routines return the integer <STRONG>ERR</STRONG> upon failure and an
integer value other than <STRONG>ERR</STRONG> upon successful completion
(the number of characters retrieved, exclusive of the
trailing 0).
No error conditions are defined. If the <EM>chstr</EM> parameter
is null, no data is returned, and the return value is ze-
ro.
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.
</PRE>
<H2>NOTES</H2><PRE>
Note that all routines except <STRONG>winchnstr</STRONG> may be macros.
SVr4 does not document whether the result string is zero-
terminated; it does not document whether a length limit
argument includes any trailing 0; and it does not document
the meaning of the return value.
</PRE>
<H2>PORTABILITY</H2><PRE>
These functions are described in the XSI Curses standard,
Issue 4. It is no more specific than the SVr4 documenta-
tion on the trailing 0. It does specify that the success-
ful return of the functions is <STRONG>OK</STRONG>.

brary are described in <STRONG><A HREF="curs_in_wchstr.3x.html">curs_in_wchstr(3x)</A></STRONG>.
