/*
* Registry Functions
*
* Copyright 1996 Marcus Meissner
* Copyright 1998 Matthew Becker
*
* December 21, 1997 - Kevin Cozens
* Fixed bugs in the _w95_loadreg() function. Added extra information
* regarding the format of the Windows '95 registry files.
*
* NOTES
* When changing this file, please re-run the regtest program to ensure
* the conditions are handled properly.
*
* TODO
* Security access
* Option handling
* Time for RegEnumKey*, RegQueryInfoKey*

* Structure of a win95 registry database.
* main header:
* 0 : "CREG" - magic
* 4 : DWORD version
* 8 : DWORD offset_of_RGDB_part
* 0C..0F: ? (someone fill in please)
* 10: WORD number of RGDB blocks
* 12: WORD ?
* 14: WORD always 0000?
* 16: WORD always 0001?
* 18..1F: ? (someone fill in please)
*
* 20: RGKN_section:
* header:
* 0 : "RGKN" - magic
* 4 : DWORD offset to first RGDB section
* 8 : DWORD offset to the root record
* C..0x1B: ? (fill in)
* 0x20 ... offset_of_RGDB_part: Disk Key Entry structures
*
* Disk Key Entry Structure:
* 00: DWORD - Free entry indicator(?)
* 04: DWORD - Hash = sum of bytes of keyname
* 08: DWORD - Root key indicator? unknown, but usually 0xFFFFFFFF on win95 systems
* 0C: DWORD - disk address of PreviousLevel Key.
* 10: DWORD - disk address of Next Sublevel Key.
* 14: DWORD - disk address of Next Key (on same level).
* DKEP>18: WORD - Nr, Low Significant part.
* 1A: WORD - Nr, High Significant part.
*
* The disk address always points to the nr part of the previous key entry
* of the referenced key. Don't ask me why, or even if I got this correct
* from staring at 1kg of hexdumps. (DKEP)
*
* The High significant part of the structure seems to equal the number
* of the RGDB section. The low significant part is a unique ID within
* that RGDB section
*
* There are two minor corrections to the position of that structure.
* 1. If the address is xxx014 or xxx018 it will be aligned to xxx01c AND
* the DKE reread from there.
* 2. If the address is xxxFFx it will be aligned to (xxx+1)000.
* CPS - I have not experienced the above phenomenon in my registry files
*
* RGDB_section:
* 00: "RGDB" - magic
* 04: DWORD offset to next RGDB section
* 08: DWORD ?
* 0C: WORD always 000d?
* 0E: WORD RGDB block number
* 10: DWORD ? (equals value at offset 4 - value at offset 8)
* 14..1F: ?
* 20.....: disk keys
*
* disk key:
* 00: DWORD nextkeyoffset - offset to the next disk key structure
* 08: WORD nrLS - low significant part of NR
* 0A: WORD nrHS - high significant part of NR
* 0C: DWORD bytesused - bytes used in this structure.
* 10: WORD name_len - length of name in bytes. without \0
* 12: WORD nr_of_values - number of values.
* 14: char name[name_len] - name string. No \0.
* 14+name_len: disk values
* nextkeyoffset: ... next disk key
*
* disk value:
* 00: DWORD type - value type (hmm, could be WORD too)
* 04: DWORD - unknown, usually 0
* 08: WORD namelen - length of Name. 0 means name=NULL
* 0C: WORD datalen - length of Data.
* 10: char name[namelen] - name, no \0
* 10+namelen: BYTE data[datalen] - data, without \0 if string
* 10+namelen+datalen: next values or disk key
*
* Disk keys are layed out flat ... But, sometimes, nrLS and nrHS are both
* 0xFFFF, which means skipping over nextkeyoffset bytes (including this
* structure) and reading another RGDB_section.
* repeat until end of file.
*
* An interesting relationship exists in RGDB_section. The value at offset
* 10 equals the value at offset 4 minus the value at offset 8. I have no
* idea at the moment what this means. (Kevin Cozens)
*
* FIXME: this description needs some serious help, yes.

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