bug in _nc_timed_wait ncurses 5.7

[David Grothe]

In file ncurses/tty/lib_twait.c line 251 '&' is used without proper ()-s.

                   if (fds[c].fd == ev->data.fev.fd
                       && fds[c].revents & POLLIN) {

Question:  Is there documentation somewhere for wgetch_events() and its 
event list parameter?

Thanks,
Dave
