/* Purpose: support for loading savefiles -BEN- */

#include "angband.h"


/*
 * This file loads savefiles from Angband 2.7.X and 2.8.X
 *
 * Ancient savefiles (pre-2.7.0) are loaded by another file.
 *
 * Note that Angband 2.7.0 through 2.7.3 are now officially obsolete,
 * and savefiles from those versions may not be successfully converted.
 *
 * We attempt to prevent corrupt savefiles from inducing memory errors.
 *
 * Note that this file should not use the random number generator, the
 * object flavors, the visual attr/char mappings, or anything else which
 * is initialized *after* or *during* the "load character" function.
 *
 * This file assumes that the creature/object records are initialized
 * to zero, and the race/kind tables have been loaded correctly.  The
 * order of object stacks is currently not saved in the savefiles, but
 * the "next" pointers are saved, so all necessary knowledge is present.
 *
 * We should implement simple "savefile extenders" using some form of
 * "sized" chunks of bytes, with a {size,type,data} format, so everyone
 * can know the size, interested people can know the type, and the actual
 * data is available to the parsing routines that acknowledge the type.
 *
 * Consider changing the "globe of invulnerability" code so that it
 * takes some form of "maximum damage to protect from" in addition to
 * the existing "number of turns to protect for", and where each hit
 * by a creature will reduce the shield by that amount.
