[fpc-pascal] How to translate C macro

Could someone suggest how to translate the following code to pascal?
#define prev(X) ( *( (void **) ( ((void *) (X)) - 32 ) ) )
prev(ptr) = prev(last);
I tried converting the macro to an inline function but I get the error
message: Error: Argument cannot be assigned to.
The following does work but is a bit verbose. So therefore I would
prefer a clean solution if possible. I never have used macro's in FPC,
are they capable of doing the same as mentioned above?
( ppointer ( (pointer (ptr)) - 32 ) )^ := ( ppointer ( (pointer
(last)) - 32 ) )^;
Thanks in advance!
