These routines return a string of characters in <EM>str</EM>,
extracted starting at the current cursor position in the
named window. Attributes are stripped from the charac-
(exclusive of the trailing NUL).

All of the functions return <STRONG>ERR</STRONG> upon failure, or the num-
ber of characters actually read into the string.
+ X/Open Curses defines no error conditions. In this imple-
+ mentation:

+ <STRONG>o</STRONG> If the <EM>win</EM> parameter is null, an error is returned,

+ <STRONG>o</STRONG> If the <EM>chstr</EM> parameter is null, an error is returned,
+
+ 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>winnstr</STRONG> may be macros.

- The XSI Curses error conditions <STRONG>EILSEQ</STRONG> and <STRONG>EILOVERFLOW</STRONG>
- associated with extended-level conformance are not yet
- detected (this implementation does not yet support XPG4
- multibyte characters). SVr4 does not document whether a
- length limit includes or excludes the trailing NUL.

+ SVr4 does not document whether a length limit includes or
+ excludes the trailing NUL.
The ncurses library extends the XSI description by allow-
ing a negative value for <EM>n</EM>. In this case, the functions
return the string ending at the right margin.
