<H2>PORTABILITY</H2><PRE>
These functions are described in the XSI Curses standard,
Issue 4. They read single-byte characters only. The
- standard does not define any error conditions. This
- implementation returns ERR if the window pointer is null,
- or if the lower-level <STRONG>wgetch</STRONG> call returns an ERR.

SVr3 and early SVr4 curses implementations did not reject
function keys; the SVr4.0 documentation claimed that "spe-
cial keys" (such as function keys, "home" key, "clear"
- key, <EM>etc</EM>.) are interpreted" without giving details. It
+ key, <EM>etc</EM>.) are "interpreted", without giving details. It
lied. In fact, the `character' value appended to the
string by those implementations was predictable but not
useful (being, in fact, the low-order eight bits of the
key's KEY_ value).
- The functions <STRONG>getnstr</STRONG>, <STRONG>mvgetnstr</STRONG>, and <STRONG>mvwgetnstr</STRONG> were pre-
- sent but not documented in SVr4.
