- <H2>DESCRIPTION</H2><PRE>
- 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-
- ters. 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 NUL).
- </PRE>
- <H2>RETURN VALUE</H2><PRE>
- All of the functions return <STRONG>ERR</STRONG> upon failure, or the num-
- ber of characters actually read into the string.
- X/Open defines no error conditions. In this implementa-
- tion, if the window parameter is null or the str parameter
- is null, a zero is returned.
- </PRE>
- <H2>NOTES</H2><PRE>
- Note that all routines except <STRONG>winnstr</STRONG> may be macros.
- </PRE>
- <H2>PORTABILITY</H2><PRE>
- 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.
