Posting an array to PNaCl module and working with it there

[Tal Glozman]

I'm trying to put all the values from an pp::VarArray variable into a local array, I have this so far:

     virtual void HandleMessage(const pp::Var& message) {
            // is array condition
            if (message.is_array()) {
                PostMessage(pp::Var("I'm in is_array condition"));
   
                // get the object
                pp::VarArray array(message);
   
                // get the first elemet of the Object, which is an array into a new array
                pp::VarArray newArray = pp::VarArray(array.Get(0));
   
                // Use the object and array
                // the size of the object
                int32_t arrayObjectSize = array.GetLength(); // important for the last job number 4 to loop and create the lenth variables for the 2 arrays
                PostMessage(pp::VarArray(array));
                PostMessage(pp::Var("the size of the object array: " + std::to_string(arrayObjectSize)));
   
                int32_t newArraySize = newArray.GetLength();
                PostMessage(pp::VarArray(newArray));
                PostMessage(pp::Var("the size of the object array: " + std::to_string(newArraySize)));
                PostMessage(newArray.Get(0));
 
   
                int32_t size = 50;
                int32_t unsortedArray[size];
   
                for (int32_t i = 0; i < size; ++i){
                     unsortedArray[i] = newArray.Get(i);
                }
           }
      }

I can't get it done with the loop i'm getting a compile error:

    job2.cc:104:35: error: assigning to 'int32_t' (aka 'int') from incompatible type 'pp::Var'
                     unsortedArray[i] = newArray.Get(i);
                                      ^ ~~~~~~~~~~~~~~~

Does any one know how I can get those 50 elements from the `pp::VarArray newArray` into this local `unsortedArray`?

Get is returning you a `Var` object. If you want to get integer
value of the `Var` you need to call `AsInt()` on it. You can also use
`is_int()` to check the type of the boxed value.
