<H2>PORTABILITY</H2><PRE>
These functions are described in the XSI Curses standard,
Issue 4. They read single-byte characters only. The
- standard specifies that they return <B>ERR</B> on failure, but
- the single error condition <B>EOVERFLOW</B> associated with
- extended-level conformance is not yet returned (the XSI
- curses support for multi-byte characters is not yet pre-
- sent).
-
+ 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, <I>etc</I>.) 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).

sent but not documented in SVr4.
