I'd like to provide some fixes for packages that are headers for c
libraries. When and should I use the "var" argument for function
arguments that return a value, or should I always use pointers
(excluding arguments that might accept nil)?
Eg:
function Foo(var A: Integer): Integer;
vs
function Foo(A: PInteger): Integer;
It's best to use pointers, but you can always provide overloads with var
arguments.
And as Dmitry Boyarintsev pointed out, don't change existing signatures for
backwards compatibility.
