- * Hook calling conventions:
- * A0 - pointer to hook data structure itself
- * A1 - pointer to parameter structure ("message") typically
- * beginning with a longword command code, which makes
- * sense in the context in which the hook is being used.
- * A2 - Hook specific address data ("object," e.g, GadgetInfo)
- *
- * Control will be passed to the routine h_Entry. For many
- * High-Level Languages (HLL), this will be an assembly language
- * stub which pushes registers on the stack, does other setup,
- * and then calls the function at h_SubEntry.
- *
- * The C standard receiving code is:
- * CDispatcher( hook, object, message )
- * struct Hook *hook;
- * APTR object;
- * APTR message;
- *
- * NOTE that register natural order differs from this convention
- * for C parameter order, which is A0,A2,A1.
- *
- * The assembly language stub for "vanilla" C parameter conventions
- * could be:
-
- _hookEntry:
- move.l a1,-(sp) ; push message packet pointer
- move.l a2,-(sp) ; push object pointer
- move.l a0,-(sp) ; push hook pointer
- move.l h_SubEntry(a0),a0 ; fetch C entry point ...
- jsr (a0) ; ... and call it
- lea 12(sp),sp ; fix stack
- rts
-
- * with this function as your interface stub, you can write
- * a Hook setup function as:
-
- SetupHook( hook, c_function, userdata )
- struct Hook *hook;
- ULONG (*c_function)();
- VOID *userdata;
-
- ULONG (*hookEntry)();
-
- hook->h_Entry = hookEntry;
- hook->h_SubEntry = c_function;
- hook->h_Data = userdata;
-
-
- * with Lattice C pragmas, you can put the C function in the
- * h_Entry field directly if you declare the function:
-
- ULONG __saveds __asm
- CDispatcher( register __a0 struct Hook *hook,
- register __a2 VOID *object,
- register __a1 ULONG *message );

- { PackTable definition:
- *
- * The PackTable is a simple array of LONGWORDS that are evaluated by
- * PackStructureTags() and UnpackStructureTags().
- *
- * The table contains compressed information such as the tag offset from
- * the base tag. The tag offset has a limited range so the base tag is
- * defined in the first longword.
- *
- * After the first longword, the fields look as follows:
- *
- * +--------- 1 = signed, 0 = unsigned (for bits, 1=inverted boolean)
- * |
- * | +------ 00 = Pack/Unpack, 10 = Pack, 01 = Unpack, 11 = special
- * | / \
- * | | | +-- 00 = Byte, 01 = Integer, 10 = Long, 11 = Bit
- * | | | / \
- * | | | | | /----- For bit operations: 1 = TAG_EXISTS is TRUE
- * | | | | | |
- * | | | | | | /-------------------- Tag offset from base tag value
- * | | | | | | | \
- * m n n o o p q q q q q q q q q q r r r s s s s s s s s s s s s s
- * \ | | |
- * Bit offset (for bit operations) ----/ | |
- * \ |
- * Offset into data structure -----------------------------------/
- *
- * A -1 longword signifies that the next longword will be a new base tag
- *
- * A 0 longword signifies that it is the end of the pack table.
- *
- * What this implies is that there are only 13-bits of address offset
- * and 10 bits for tag offsets from the base tag. For most uses this
- * should be enough, but when this is not, either multiple pack tables
- * or a pack table with extra base tags would be able to do the trick.
- * The goal here was to make the tables small and yet flexible enough to
- * handle most cases.

- { Some handy dandy macros to easily create pack tables
- *
- * Use PACK_STARTTABLE() at the start of a pack table. You pass it the
- * base tag value that will be handled in the following chunk of the pack
- * table.
- *
- * PACK_ENDTABLE() is used to mark the end of a pack table.
- *
- * PACK_NEWOFFSET() lets you change the base tag value used for subsequent
- * entries in the table
- *
- * PACK_ENTRY() lets you define an entry in the pack table. You pass it the
- * base tag value, the tag of interest, the type of the structure to use,
- * the field name in the structure to affect and control bits (combinations of
- * the various PKCTRL_XXX bits)
- *
- * PACK_BYTEBIT() lets you define a bit-control entry in the pack table. You
- * pass it the same data as PACK_ENTRY, plus the flag bit pattern this tag
- * affects. This macro should be used when the field being affected is byte
- * sized.
- *
- * PACK_WORDBIT() lets you define a bit-control entry in the pack table. You
- * pass it the same data as PACK_ENTRY, plus the flag bit pattern this tag
- * affects. This macro should be used when the field being affected is Integer
- * sized.
- *
- * PACK_LONGBIT() lets you define a bit-control entry in the pack table. You
- * pass it the same data as PACK_ENTRY, plus the flag bit pattern this tag
- * affects. This macro should be used when the field being affected is longword
- * sized.
- *
- * EXAMPLE:
- *
- * ULONG packTable[] =
- * (
- * PACK_STARTTABLE(GA_Dummy),
- * PACK_ENTRY(GA_Dummy,GA_Left,Gadget,LeftEdge,PKCTRL_WORD|PKCTRL_PACKUNPACK),
- * PACK_ENTRY(GA_Dummy,GA_Top,Gadget,TopEdge,PKCTRL_WORD|PKCTRL_PACKUNPACK),
- * PACK_ENTRY(GA_Dummy,GA_Width,Gadget,Width,PKCTRL_UWORD|PKCTRL_PACKUNPACK),
- * PACK_ENTRY(GA_Dummy,GA_Height,Gadget,Height,PKCTRL_UWORD|PKCTRL_PACKUNPACK),
- * PACK_WORDBIT(GA_Dummy,GA_RelVerify,Gadget,Activation,PKCTRL_BIT|PKCTRL_PACKUNPACK,GACT_RELVERIFY)
- * PACK_ENDTABLE
- * );
