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