<BODY>
<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 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 is-
+ sue 7 revised the corresponding description of <STRONG>wgetnstr</STRONG> to address this
+ issue. The unrevised description of <STRONG>wget_nwstr</STRONG> can be interpreted ei-
+ ther way. This implementation counts the terminator in the length.
+
+ X/Open Curses does not specify what happens if the length <EM>n</EM> is nega-
+ tive.
+
+ <STRONG>o</STRONG> For analogy with <STRONG>wgetnstr</STRONG>, ncurses 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 ncurses 6.1 in this regard, treating a <STRONG>-1</STRONG>
+ as an indefinite number of characters.
