ChunkArrayHeader

typedef struct {
word	CAH_count;			/* # of elements in chunk array */
word	CAH_elementSize;			/* Size of each element (in bytes) */
word	CAH_curOffset;			/* For internal use only */
word	CAH_offset;			/* Offset from start of chunk to first element */
} ChunkArrayHeader;

Every chunk array begins with a ChunkArrayHeader . This structure contains information about the chunk array. Applications should never change the contents of the ChunkArrayHeader ; only the chunk array routines should do this. However, applications can examine the header if they wish.

Contents: There are four word-length fields in the ChunkArrayHeader:

CAH _count

This word contains the number of elements in the chunk array.

CAH _elementSize

This word contains the size of each element (in bytes). If the elements are variable-sized, CAH_elementSize will be zero.

CAH _curOffset

This word is used by ChunkArrayEnum() for bookkeeping.

CAH _offset

This is the offset from the start of the chunk to the first element in the array.

Chunk handles are offsets into a local memory heap. To find the current

ChunkHandle

typedef word ChunkHandle;

location of a chunk in an LMem heap, combine the segment address of the heap with the chunk handle. From this location you can read the current offset of the chunk itself.

See Also: optr,LMemDeref().

ChunkMapList

typedef struct {
word	CML_source;
word	CML_dest;
} ChunkMapList;

 

ClassFlags

typedef ByteFlags ClassFlags;
#define CLASSF_HAS_DEFAULT						0x80
#define CLASSF_MASTER_CLASS 						0x40
#define CLASSF_VARIANT_CLASS 						0x20
#define CLASSF_DISCARD_ON_SAVE 						0x10
#define CLASSF_NEVER_SAVED						0x08
#define CLASSF_HAS_RELOC 						0x04
#define CLASSF_C_HANDLERS 						0x02

This record is stored in the ClassStruct structure's Class_flags field. These flags are internal and may not be set or retrieved directly. See the entry on @class for more information about these flags.

ClassStruct

typedef	struct	_ClassStruct {
struct _ClassStruct *Class_superClass;		/* superclass pointer */
word		Class_masterOffset;					/* offset to master offset in chunk */
word 		Class_methodCount;					/* number of methods in this class */
word 		Class_instanceSize;					/* size of entire master group */
word 		Class_vdRelocTable;					/* offset to vardata relocation table */
word 		Class_relocTable;					/* offset to relocation table */
ClassFlags 		Class_flags;					/* a record of ClassFlags */
byte 		Class_masterMessages;					/* internal flags for optimization */
} ClassStruct;

This is the structure that defines a class. It is internal and used only very rarely by anything other than the kernel and the UI.
