</PRE>
<H2>DESCRIPTION</H2><PRE>
These routines are included as a conversion aid for pro-
grams that use the <I>termcap</I> library. Their parameters are
the same and the routines are emulated using the <I>terminfo</I>
database. Thus, they can only be used to query the capa-
bilities of entries for which a terminfo entry has been
compiled.
The <B>tgetent</B> routine loads the entry for <I>name</I>. It returns
1 on success, 0 if there is no such entry, and -1 if the
terminfo database could not be found. The emulation
ignores the buffer pointer <I>bp</I>.
The <B>tgetflag</B> routine gets the boolean entry for <I>id</I>, or
zero if it is not available.
The <B>tgetnum</B> routine gets the numeric entry for <I>id</I>, or -1
if it is not available.
The <B>tgetstr</B> routine returns the string entry for <I>id</I>, or
zero if it is not available. Use <B>tputs</B> to output the
returned string. The return value will also be copied to
the buffer pointed to by <I>area</I>, and the <I>area</I> value will be
updated to point past the null ending this value.
The <B>tgoto</B> routine instantiates the parameters into the
given capability. The output from this routine is to be
passed to <B>tputs</B>.
The <B>tputs</B> routine is described on the <B><A HREF="curs_terminfo.3x.html">curs_terminfo(3x)</A></B>
manual page. It can retrieve capabilities by either term-
cap or terminfo name.
</PRE>
<H2>RETURN VALUE</H2><PRE>
Except where explicitly noted, routines that return an
integer return <B>ERR</B> upon failure and <B>OK</B> (SVr4 only speci-
fies "an integer value other than <B>ERR</B>") upon successful
completion.
Routines that return pointers return <B>NULL</B> on error.
</PRE>
<H2>BUGS</H2><PRE>
If you call <B>tgetstr</B> to fetch <B>ca</B> or any other parameterized
string, be aware that it will be returned in terminfo
notation, not the older and not-quite-compatible termcap
notation. This won't cause problems if all you do with it
is call <B>tgoto</B> or <B>tparm</B>, which both expand terminfo-style.
Because terminfo conventions for representing padding in
string capabilities differ from termcap's, <B>tputs("50");</B>
will put out a literal "50" rather than busy-waiting for
50 milliseconds. Cope with it.
</PRE>
<H2>PORTABILITY</H2><PRE>
The XSI Curses standard, Issue 4 describes these func-
tions. However, they are marked TO BE WITHDRAWN and may
be removed in future versions.
Neither the XSI Curses standard nor the SVr4 man pages
documented the return values of <B>tgetent</B> correctly, though
all three were in fact returned ever since SVr1.
