* tgetent(bufp, term)
*
* In termcap, this function reads in the entry for terminal `term' into the
* buffer pointed to by bufp. It must be called before any of the functions
* below are called.
* In this terminfo emulation, tgetent() simply calls setupterm() (which
* does a bit more than tgetent() in termcap does), and returns its return
* value (1 if successful, 0 if no terminal with the given name could be
* found, or -1 if no terminal descriptions have been installed on the
* system). The bufp argument is ignored.
