Hi All,

Also, I usually use pointer to pass block of memory to functions. How
do I implement a function with the following signature:
procedure MyProc(var Buf; Len: Integer):
I mean, how to handle "var Buf" inside the procedure body?
You can take the address of the Buf variable by using @Buf. For example:
procedure MyProc(var Buf; Len: Integer);
var
I: Integer;
P: PByte;
begin
P := @Buf;
for I := 0 to Len - 1 do
(P+I)^ := 0;
end;
