The tgetent routine loads the entry for name. It returns:
1 on success,
0 if there is no such entry (or that it is a generic type, having
too little information for curses applications to run), and
-1 if the terminfo database could not be found.
This is the traditional return value, dating back to the original BSD
implementation. If HPUX does it differently, it's broken.

From 1997? Yeah, that was withdrawn.

It doesn't.
