+ These functions are described in The Single Unix Specification, Version
+ 2. No error conditions are defined. This implementation returns ERR
+ if the window pointer is null, or if the lower-level <STRONG>wget_wch</STRONG> call re-
+ turns an ERR. In the latter case, an ERR return without other data is
+ treated as an end-of-file condition, and the returned array contains a
+ <STRONG>WEOF</STRONG> followed by a null <STRONG>wchar_t</STRONG>.
+
+ 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 <EM>get</EM><STRONG>_</STRONG><EM>wstr()</EM> is as though a series of calls to
+ <EM>get</EM><STRONG>_</STRONG><EM>wch()</EM> 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.
