255 * This is strictly a core-economy kluge. The really clean way to handle
256 * compilation is to slurp the whole file into core and then do all the
257 * name-collision checks and entry writes in one swell foop. But the
258 * terminfo master file is large enough that some core-poor systems swap
259 * like crazy when you compile it this way...there have been reports of
260 * this process taking *three hours*, rather than the twenty seconds or
261 * less typical on my development box.
263 * So. This hook *immediately* writes out the referenced entry if it
264 * has no use capabilities. The compiler main loop refrains from
265 * adding the entry to the in-core list when this hook fires. If some
266 * other entry later needs to reference an entry that got written
267 * immediately, that's OK; the resolution code will fetch it off disk
268 * when it can't find it in core.
270 * Name collisions will still be detected, just not as cleanly. The
271 * write_entry() code complains before overwriting an entry that
272 * postdates the time of tic's first call to write_entry(). Thus
273 * it will complain about overwriting entries newly made during the
274 * tic run, but not about overwriting ones that predate it.
276 * The reason this is a hook, and not in line with the rest of the
277 * compiler code, is that the support for termcap fallback cannot assume
278 * it has anywhere to spool out these entries!
280 * The _nc_set_type() call here requires a compensating one in
283 * If you define HAVE_BIG_CORE, you'll disable this kluge. This will
284 * make tic a bit faster (because the resolution code won't have to do
285 * disk I/O nearly as often).
