NSZone

Legacy compatibility structure for zone-based memory allocation. In modern MulleObjC, all zone operations map to standard memory functions.

Structure

typedef struct {
    void *unused;  // Required for C11 compatibility
} NSZone;

Zone Functions

All return NULL or map to standard allocation: - NSDefaultMallocZone() - Returns NULL - NSCreateZone(startSize, granularity, canFree) - Returns NULL - NSRecycleZone(zone) - No-op - NSSetZoneName(zone, name) - No-op - NSZoneFromPointer(p) - Returns NULL

Memory Functions

Map directly to standard allocation: - NSZoneMalloc(zone, size) → mulle_malloc(size) - NSZoneCalloc(zone, numElems, byteSize) → mulle_calloc(numElems, byteSize) - NSZoneRealloc(zone, p, size) → mulle_realloc(p, size) - NSZoneFree(zone, p) → mulle_free(p)

Object Zone Access

• mulle_objc_object_zone() - Returns NULL (created by compiler for -zone)

Note: All zone functions exist only for legacy compatibility. Modern code should use standard allocation functions.
