First, that's the old termcap interface; new programs should use the
terminfo interface.

Second, the use of the "area" variable is wrong. It should be
something like:

	char buf[100];
	char *area = buf;
	
	puts(tgetstr("cl", &area));

Repeated calls to tgetstr() will advance the "area" pointer, so that
"buf" will contain, in order, all of the strings retrieved by
tgetstr().
