98 * How this initializer works:
100 * Members uid, name, file, cadef, size, and the EFF_IMMUTABLE
101 * bits of flags get their final value.
102 * If flags & EFF_STATIC, the cache is mapped here, and members
103 * cache, csize get their final value.
104 * Members baseid, cids, fids and the EFF_MEM|EFF_PRIVATE bits of
105 * flags are initialized according the initial cache contents.
106 * Member fd is initialized to -1.
107 * Members init, postread, prewrite get initialized to NULL, but
108 * that can be changed by users.
110 * Whatever of the above can't be done here must be done in
111 * empfile_init() or empfile_fixup(). Except cadef may be set in
112 * nsc_init() instead.
116 * Keep in mind that player command arguments are matched against
117 * values of member name: no whitespace there, please.
123 * All caches unmapped. EF_SECTOR gets bogus nent here. EF_MAP
124 * and EF_BMAP get a bogus size here. Fixed up by
