35 * Termcap compatibility support
37 * If your OS integrator didn't install a terminfo database, you can call
38 * _nc_read_termcap_entry() to support reading and translating capabilities
39 * from the system termcap file. This is a kludge; it will bulk up and slow
40 * down every program that uses ncurses, and translated termcap entries cannot
41 * use full terminfo capabilities. Don't use it unless you absolutely have to;
42 * instead, get your system people to run tic(1) from root on the terminfo
43 * master included with ncurses to translate it into a terminfo database.
45 * If USE_GETCAP is enabled, we use what is effectively a copy of the 4.4BSD
46 * getcap code to fetch entries. There are disadvantages to this; mainly that
47 * getcap(3) does its own resolution, meaning that entries read in in this way
48 * can't reference the terminfo tree. The only thing it buys is faster startup
49 * time, getcap(3) is much faster than our tic parser.
