69 These routines return a string of characters in <EM>str</EM>,
70 extracted starting at the current cursor position in the
71 named window. Attributes are stripped from the charac-
72 ters. The four functions with <EM>n</EM> as the last argument
73 return a leading substring at most <EM>n</EM> characters long
74 (exclusive of the trailing NUL).
77 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
78 All of the functions return <STRONG>ERR</STRONG> upon failure, or the num-
79 ber of characters actually read into the string.
81 X/Open defines no error conditions. In this implementa-
82 tion, if the window parameter is null or the str parameter
83 is null, a zero is returned.
85 Functions with a "mv" prefix first perform a cursor move-
86 ment using <STRONG>wmove</STRONG>, and return an error if the position is
87 outside the window, or if the window pointer is null.

91 Note that all routines except <STRONG>winnstr</STRONG> may be macros.

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