Introduction Datatypes have largely replaced the EA / Commodore era inspired IFF file formats. IBM has an entry about IFF file format. only some few times its called blocklen 128 bytes 1. Something FRead-ing pointers/IFF-offsets one at a time, then FRead-ing the following block of data? (Disk blocks numbers and file entries?) Especially IFF: Read FORM (LONG) Read length (LONG) Read type (LONG) Read block-length (LONG) Read block content (an even number of bytes) References struct IFFHandle *AllocIFF() () LONG OpenIFF(struct IFFHandle *iff, LONG rwMode) LONG ParseIFF(struct IFFHandle *iff, LONG mode) void CloseIFF(struct IFFHandle *iff) void FreeIFF(struct IFFHandle *iff) LONG ReadChunkBytes(struct IFFHandle *iff, APTR buf, LONG numBytes) (A0, A1, D0) LONG WriteChunkBytes(struct IFFHandle *iff, APTR buf, LONG numBytes) (A0, A1, D0) LONG ReadChunkRecords(struct IFFHandle *iff, APTR buf, LONG bytesPerRecord, LONG numRecords) (A0, A1, D0, D1) LONG WriteChunkRecords(struct IFFHandle *iff, APTR buf, LONG bytesPerRecord, LONG numRecords) (A0, A1, D0, D1) LONG PushChunk(struct IFFHandle *iff, LONG type, LONG id, LONG size) (A0, D0, D1, D2) LONG PopChunk(struct IFFHandle *iff) (A0) LONG EntryHandler(struct IFFHandle *iff, LONG type, LONG id, LONG position, struct Hook *handler, APTR object) (A0, D0, D1, D2, A1, A2) LONG ExitHandler(struct IFFHandle *iff, LONG type, LONG id, LONG position, struct Hook *handler, APTR object) (A0, D0, D1, D2, A1, A2) LONG PropChunk(struct IFFHandle *iff, LONG type, LONG id) (A0, D0, D1) LONG PropChunks(struct IFFHandle *iff, LONG *propArray, LONG numPairs) (A0, A1, D0) LONG StopChunk(struct IFFHandle *iff, LONG type, LONG id) (A0, D0, D1) LONG StopChunks(struct IFFHandle *iff, LONG *propArray, LONG numPairs) (A0, A1, D0) LONG CollectionChunk(struct IFFHandle *iff, LONG type, LONG id) (A0, D0, D1) LONG CollectionChunks(struct IFFHandle *iff, LONG *propArray, LONG numPairs) (A0, A1, D0) struct CollectionItem *FindCollection(struct IFFHandle *iff, LONG type, LONG id) (A0, D0, D1) LONG StopOnExit(struct IFFHandle *iff, LONG type, LONG id) (A0, D0, D1) struct StoredProperty *FindProp(struct IFFHandle *iff, LONG type, LONG id) (A0, D0, D1) struct ContextNode *FindPropContext(struct IFFHandle *iff) (A0) struct ContextNode *CurrentChunk(struct IFFHandle *iff) (A0) struct ContextNode *ParentChunk(struct ContextNode *contextNode) (A0) struct LocalContextItem *AllocLocalItem(LONG type, LONG id, LONG ident, ULONG dataSize) (D0, D1, D2, D3) APTR LocalItemData(struct LocalContextItem *localItem) (A0) void SetLocalItemPurge(struct LocalContextItem *localItem, struct Hook *purgeHook) (A0, A1) void FreeLocalItem(struct LocalContextItem *localItem) (A0) struct LocalContextItem *FindLocalItem(struct IFFHandle *iff, LONG type, LONG id, LONG ident) (A0, D0, D1, D2) LONG StoreLocalItem(struct IFFHandle *iff, struct LocalContextItem *localItem, LONG position) (A0, A1, D0) void StoreItemInContext(struct IFFHandle *iff, struct LocalContextItem *localItem, struct ContextNode *contextNode) (A0, A1, A2) void InitIFF(struct IFFHandle *iff, LONG flags, struct Hook *streamHook) (A0, D0, A1) void InitIFFasDOS(struct IFFHandle *iff) (A0) void InitIFFasClip(struct IFFHandle *iff) (A0) struct ClipboardHandle *OpenClipboard(LONG unitNumber) (D0) void CloseClipboard(struct ClipboardHandle *clipHandle) (A0) LONG GoodID(LONG id) (D0) LONG GoodType(LONG type) (D0) STRPTR IDtoStr(LONG id, STRPTR buf) (D0, A0)
