+ X/Open curses documented these functions to pass an array of <STRONG>wchar_t</STRONG> in
+ 1997, but that was an error because of this part of the description:
+
+ The effect of <STRONG>get_wstr</STRONG> is as though a series of calls to <STRONG>get_wch</STRONG>
+ were made, until a newline character, end-of-line character, or
+ end-of-file character is processed.
+
+ The latter function <EM>get</EM><STRONG>_</STRONG><EM>wch</EM> can return a negative value, while <STRONG>wchar_t</STRONG>
+ is a unsigned type. All of the vendors implement this using <STRONG>wint_t</STRONG>,
+ following the standard.
+
+ X/Open Curses, Issue 7 (2009) is unclear regarding whether the
+ terminating <EM>null</EM> <STRONG>wchar_t</STRONG> value is counted in the length parameter <EM>n</EM>.
+ X/Open Curses, Issue 7 revised the corresponding description of
+ <STRONG>wgetnstr</STRONG> to address this issue. The unrevised description of
+ <STRONG>wget_nwstr</STRONG> can be interpreted either way. This implementation counts
+ the terminator in the length.
+
+ X/Open Curses does not specify what happens if the length <EM>n</EM> is
+ negative.
+
+ <STRONG>o</STRONG> For analogy with <STRONG>wgetnstr</STRONG>, <EM>ncurses</EM> 6.2 uses a limit (based on
+ <STRONG>LINE_MAX</STRONG>).
+
+ <STRONG>o</STRONG> Some other implementations (such as Solaris xcurses) do the same,
+ while others (PDCurses) do not allow this.
+
+ <STRONG>o</STRONG> NetBSD 7 curses imitates <EM>ncurses</EM> 6.1 in this regard, treating a <STRONG>-1</STRONG>
+ as an indefinite number of characters.
