int alloc
(int size, int nextOutOfLineDepth)


## Implementation

```dart
int alloc(int size, int nextOutOfLineDepth) {
  if (nextOutOfLineDepth > _maxOutOfLineDepth) {
    throw FidlError('Exceeded maxOutOfLineDepth',
        FidlErrorCode.fidlExceededMaxOutOfLineDepth);
  }
  int offset = _extent;
  _claimBytes(align(size));
  return offset;
}
```
