Yet another thing, someone also mentioned this.
The cdecl calling convention corresponds to extern "C" in C++. Maybe you
are using stdcall in your C++ library?
Or perhaps you are on Linux where this is not relevant? But the extern
"C" could be relevant also on Linux.

You're right, C++ "&" is equivalent to Pascal "var".
Well, removing the "var" in the 2nd para

This is How I understand the var parameter.
It is an address, but is treated as normal variable, so it is not needed
to dereference a pointer.
For example
int f(int* x) in C/C++ corresponds to
function f(var x: integer): integer;
Now we have
int f(int x);
If you declare it as
function f(var x: i

I probably don't understand. You will be able to change it, I see no
problem. It is a local variable which can be changed.

I think you could not declare the second parameter of GetData as var
parameter. Because it is then treated as address.
I am not sure what corresponds to C++ unsigned long, perhaps LongWord?
So try to change the second parameter so that it is not a var parameter.

I'm using a C++ library with a function that receives a parameter this
way:
int getData(void * &buffer, unsigned long &bufSize){
bufSize = 10;
return 1;
}
The Pascal definition I'm using is this:
function (var buffer: pointer; var bufsize: longword): Integer; cdecl;
I'm using this library w
