</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></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). Transfer stops at the end of the current line, or when <EM>n</EM>
characters have been stored at the location referenced by <EM>chstr</EM>.
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).
X/Open Curses defines no error conditions. This implementation returns
an error
<STRONG>o</STRONG> if the <EM>win</EM> parameter is null or
<STRONG>o</STRONG> if the <EM>chstr</EM> parameter is null.
Functions prefixed with "mv" first perform cursor movement and fail if
the position (<EM>y</EM>, <EM>x</EM>) is outside the window boundaries.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
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.
Reading a line that overflows the array pointed to by <EM>chstr</EM> with
<STRONG>inchstr</STRONG>, <STRONG>mvinchstr</STRONG>, <STRONG>mvwinchstr</STRONG> or <STRONG>winchstr</STRONG> causes undefined results.
Therefore, the use of <STRONG>inchnstr</STRONG>, <STRONG>mvinchnstr</STRONG>, <STRONG>mvwinchnstr</STRONG>, or <STRONG>winchnstr</STRONG>
is recommended.
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
These functions are described in X/Open Curses, Issue 4. It is no more
specific than the SVr4 documentation on the trailing 0. It does
specify that the successful return of the functions is <STRONG>OK</STRONG>.
