xhrb object/function in c/c++ routine - xharbour

Hi,

Is it possible to create xhrb object in C routine and pass it to a xharbour
function as a parameter?
I call xharbour function in C routine and want to pass an xhr object to it
to be accesed easily in xharbour.
I'm succeed with passing an int or char* value but can't pass an object.



I'd like to have something like below:

..cpp

void cpp_function()
{

CREATE oxHrbClass object
POPULATE oxHrbClass-> value with "changed value"
CALL callback(xoHrbClass)

}


..prg
PROCEDURE CALLBACK ( oxHrbClass)
? oxHrbClass:value
RETURN

CLASS xHrbClass
DATA value INIT "init value"
ENDCLASS



Thanks in advance for any tips
Rafal
