Delphi Compiler Error
H2244 Pointer expression needs no Initialize/Finalize – need ^ operator?
Reason for the Error & Solution
You have attempted to finalize a Pointer type.
program Produce;
var
str : String;
pstr : PString;
begin
str := 'Sharene';
pstr := @str;
Finalize(pstr); (*note: do not attempt to use 'str' after this*)
end.
In this example the pointer, pstr, is passed to the Finalize procedure. This causes an hint since pointers do not require finalization.
program Solve;
var
str : String;
pstr : PString;
begin
str := 'Sharene';
pstr := @str;
Finalize(pstr^); (*note: do not attempt to use 'str' after this*)
end.
The solution to this problem is to apply the ^ operator to the pointer which is passed to the Finalization procedure.
