-<H2>DESCRIPTION</H2><PRE>
- These routines are included as a conversion aid for pro-
- grams that use the <EM>termcap</EM> library. Their parameters are
- the same and the routines are emulated using the <EM>terminfo</EM>
- database. Thus, they can only be used to query the capa-
- bilities of entries for which a terminfo entry has been
- compiled.
-
- The <STRONG>tgetent</STRONG> routine loads the entry for <EM>name</EM>. 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 <EM>bp</EM>.
-
- The <STRONG>tgetflag</STRONG> routine gets the boolean entry for <EM>id</EM>, or
- zero if it is not available.
-
- The <STRONG>tgetnum</STRONG> routine gets the numeric entry for <EM>id</EM>, or -1
- if it is not available.
-
- The <STRONG>tgetstr</STRONG> routine returns the string entry for <EM>id</EM>, or
- zero if it is not available. Use <STRONG>tputs</STRONG> to output the
- returned string.
-
- The <STRONG>tgoto</STRONG> routine instantiates the parameters into the
- given capability. The output from this routine is to be
- passed to <STRONG>tputs</STRONG>.
-
- The <STRONG>tputs</STRONG> routine is described on the <STRONG><A HREF="curs_terminfo.3x.html">curs_terminfo(3X)</A></STRONG>
- manual page. It can retrieve capabilities by either term-
- cap or terminfo name.

-<H2>RETURN VALUE</H2><PRE>
- Except where explicitly noted, routines that return an
- integer return <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> (SVr4 only speci-
- fies "an integer value other than <STRONG>ERR</STRONG>") upon successful
- completion.
-
- Routines that return pointers return <STRONG>NULL</STRONG> on error.
- If you call <STRONG>tgetstr</STRONG> to fetch <STRONG>ca</STRONG> 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 <STRONG>tgoto</STRONG> or <STRONG>tparm</STRONG>, which both expand terminfo-style.
-
- Because terminfo conventions for representing padding in
- string capabilities differ from termcap's, <STRONG>tputs("50");</STRONG>
- 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 However, they are marked TO BE WITHDRAWN and may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 <STRONG>tgetent</STRONG> correctly, though
- all three were in fact returned ever since SVr1.
