Calling a function on an object passed as argument

Question

Hi everyone,
i'm trying to call an actionscript function on an object passed as argument to a c function. Here are how I do :
I have a class named test_class implemented as
package
     public class test_class
          public var bliblou:int;
and a C function that have to modify the bliblou var of an test_class object passed as argument. Here is my function :
static AS3_Val test_obj_param( void* self, AS3_Val args )
     AS3_Val obj;
     AS3_ArrayValue( args, "AS3ValType ", &obj );
     AS3_Set( obj, AS3_String("bliblou"), AS3_Int( 123456 ) );
     return AS3_Null();
Then I call the function in my actionscript main function like this :
var loader:CLibInit = new CLibInit;
var lib:Object = loader.init();
var test:test_class = new test_class();
lib.test_obj_param( test );
But when the test_obj_param is trying to run, I obtain an error saying "unable to access a propriety of a null object".
What am I doing wrong ? Is it possible to do what I try to (calling a function on an object passed as argument) ?
Thanks in advance

After a long trip to Alchemy possibilities and a lot of tests I have finally found a solution to my question.
Instead of using AS3ArrayValue to get my objet, I use the AS3 function shift on the args array to get my object. Here is how I do
static AS3_Val test_obj_param( void* self, AS3_Val args )
     AS3_Val emptyParams = AS3_Array("");
     AS3_Val obj = AS3_CallS( "shift", args, emptyParams );
     AS3_SetS( obj, "bliblou", AS3_Int( 123456 ) );
     AS3_Release(emptyParams);
     return AS3_NULL();
Maybe there is a bug in the AS3ValType getter.
