untyped Pointer in structures
Notice to: "structure TWindow field WScreen" and all the others of this kind: You will find dozens of this kind in any kind of structures. The reason are recursive type definitions which does work little bit strange in Pascal. Forwarding of types only within the same Block. So this works:
type
PScreen = ^TScreen;
PWindow = ^TWindow;
TWindow = record
WScreen: PScreen
end;
TScreen = record
FirstWindow: PWindow;
end;
const
IDCMP_NEWSIZE = 1 shl 1;
and this does not work:
type
PScreen = ^TScreen;
PWindow = ^TWindow;
TWindow = record
WScreen: PScreen
end;
const
IDCMP_NEWSIZE = 1 shl 1;
type
TScreen = record
FirstWindow: PWindow;
end;
So a complete Rewrite/Resort of the complete unit is needed, as I did for AROS. I will not do that for MorphOS/Amiga again. --ALB42 (talk) 13:03, 27 September 2015 (CEST)
