Forward declarations for record types

Question

Is there such a thing as in the title? I\'m trying to do this in part of converting an API structure, and run into something I haven\'t encountered before:

Answer 1

I think this is the simplest solution:

PFNReaderTranslatedDispatch = function(var msg: TMsg): BOOL; stdcall;
PReaderModeInfo = ^TReaderModeInfo;
PFNReaderScroll = function(prmi: PReaderModeInfo; dx, dy: integer): BOOL; stdcall;
TReaderModeInfo = record
  cbSize: DWord;
  hWnd: THandle;
  fFlags: DWord;
  prc: PRect;
  pfnScroll: PFNReaderScroll;
  fFlags2: PFNReaderTranslatedDispatch;
  lParam: DWord;
end;

Indeed, you can clearly reaplce a var parameter by a (by-value) pointer parameter. And there is no problem declaring PReaderModeInfo before TReaderModeInfo.
