 235     reghack - windows 3.11 registry data format demo program.
 236
 237     The reg.dat file has 3 parts, a header, a table of 8-byte entries that is
 238     a combined hash table and tree description, and finally a text table.
 239
 240     The header is obvious from the struct header. The taboff1 and taboff2
 241     fields are always 0x20, and their usage is unknown.
 242
 243     The 8-byte entry table has various entry types.
 244
 245     tabent[0] is a root index. The second word has the index of the root of
 246             the directory.
 247     tabent[1..hashsize] is a hash table. The first word in the hash entry is
 248             the index of the key/value that has that hash. Data with the same
 249             hash value are on a circular list. The other three words in the
 250             hash entry are always zero.
 251     tabent[hashsize..tabcnt] is the tree structure. There are two kinds of
 252             entry: dirent and keyent/valent. They are identified by context.
 253     tabent[freeidx] is the first free entry. The first word in a free entry
 254             is the index of the next free entry. The last has 0 as a link.
 255             The other three words in the free list are probably irrelevant.
 256
 257     Entries in text table are preceded by a word at offset-2. This word
 258     has the value (2*index)+1, where index is the referring keyent/valent
 259     entry in the table. I have no suggestion for the 2* and the +1.
 260     Following the word, there are N bytes of data, as per the keyent/valent
 261     entry length. The offset of the keyent/valent entry is from the start
 262     of the text table to the first data byte.
 263
 264     This information is not available from Microsoft. The data format is
 265     deduced from the reg.dat file by me. Mistakes may
 266     have been made. I claim no rights and give no guarantees for this program.

 504  * the 1st entry in a "usual" registry file is a nul-entry with subkeys: the
 505  * hive itself. It looks the same like other keys. Even the ID-number can
 506  * be any value.
 507  *
 508  * The "hash"-value is a value representing the key's name. Windows will not
 509  * search for the name, but for a matching hash-value. if it finds one, it
 510  * will compare the actual string info, otherwise continue with the next key.
 511  * To calculate the hash initialize a D-Word with 0 and add all ASCII-values
 512  * of the string which are smaller than 0x80 (128) to this D-Word.
 513  *
 514  * If you want to modify key names, also modify the hash-values, since they
 515  * cannot be found again (although they would be displayed in REGEDIT)
 516  * End of list-pointers are filled with 0xFFFFFFFF
 517  *
 518  * Disk keys are layed out flat ... But, sometimes, nrLS and nrMS are both
 519  * 0xFFFF, which means skipping over nextkeyoffset bytes (including this
 520  * structure) and reading another RGDB_section.
 521  *
 522  * The last DKE (see field last_dke in _w95_rgkn) has only 3 DWORDs with
 523  * 0x80000000 (EOL indicator ?) as x1, the hash value and 0xFFFFFFFF as x3.
 524  * The remaining space between last_dke and the offset calculated from
 525  * rgkn->size seems to be free for use for more dke:s.
 526  * So it seems if more dke:s are added, they are added to that space and
 527  * last_dke is grown, and in case that "free" space is out, the space
 528  * gets grown and rgkn->size gets adjusted.
