I haven't tried it, but if a 'Address is the same size as an Access type, and has the same value, then you may be able to   
do the following: 
 
function C_Function ( value : in Integer; Result : in System.Address ) return System.Address; 
 
Then, just use Unchecked conversion to convert the result to an Access type, and access it that way.
