XFDMASTERNAME	MACRO

		ENDM

** Let's start with the library base. There's not too much in it...

		rsset	34	;standard lib base
dc_seglist	rs.l	1	;segment list of library (private)
dc_DOSBase	rs.l	1	;DOSBase, can be used (no problemo)
dc_crunchlist	rs.l	1	;ptr to crunchliststruc (first entry!private?!?)
dc_sizeof	=	__RS

** Ok, now let's come to the CrunchInfo(BI) structure.
** There is also another structure called SI, but don't ask me for the USE

		rsreset
bi_data		rs.l	1	; pointer to crunched file
bi_len		rs.l	1	; length of crunched file
bi_strucptr	rs.l	1	; ptr to crunchlist (actual entry!private?!?)
bi_packname	rs.l	1	; ptr to name of cruncher
bi_packtype	rs.w	1	; type of packer (look at packtypes)
bi_err		rs.w	1	; error nr for use with _LVOGetError()
bi_depackbuf	rs.l	1	; ptr to depacked datas
bi_unknown	rs.l	1	; ???
bi_depacklen	rs.l	1	; bufferlen (memory usage for imp etc)
bi_reallen	rs.l	1	; real decrunched filelen!!!
bi_decrunchadr	rs.l	1	; decrunchadress (pt_absolut ONLY)
bi_jumpadr	rs.l	1	; jumpdress (pt_absolut ONLY)
bi_unknown2	rs.l	1	; ???
bi_sizeof	=	__RS

** packertypes 
pt_reloc	=	1
pt_absolut	=	2
pt_data		=	4

pt_encrypt	=	$10		;can be logical ored to the other ones


** Library vector offsets for this release. See them as constants for
** further updates.
_LVOAllocBI=-30			; IN:		  OUT:d0=ptr 2 alloc
_LVOFreeBI=-36			; IN:a1=ptr alloc OUT:

_LVOAllocSI=-42			; like AllocBI
_LVOFreeSI=48			; like FreeBI

_LVOGetCruncher=-54		; IN:a0=BI	  OUT:d0=0(fail) or 1(packed)
_LVODecrunch=-60		; IN:a0=BI	  OUT=d0=0 or error

** the next two offsets are not tested yet. please use them carefully...
**
_LVOGetCruncherSI=-66		; IN:a0=ptrSI???  OUT d0=0(fail) or ???
_LVODecrunchSI=-72		; IN:a0=ptrSI???  OUT d0=0(fail) or ???

_LVOGetError=-78		; IN:d0=errnum	  OUT:a0=ptr->errstring
_LVOTestHunkStructure=-84	; IN:a0=ptr->file OUT:d0=0(fail) or 1(ok)

** last but not least a short description of the library-internal
** cruncher-list. (private or not private, that's the question :-)
