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><a name="h2-RETURN-VALUE">RETURN VALUE</a></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.

|
|
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.

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>.
