My original c++  function had the following signature

unsigned char* random(int length);

To use this as an add-on I modified it to 

Handle<Value> random(const Arguments& args) {


if(args[0]->IsInt32()){

Local<Int32> length = args[0]->ToInt32();

// Now here I want to create an array like this "unsigned char* buffer = 
new unsigned char[length];"  using the length variable
// but it gives me an error saying length is undefined

//1.  how do I convert Local<Int32> to int ???
// 2. How to return the array from this function??


}

}
