How can I return multiple incomplete types in C?

I am new to C and trying out Tensorflow in C. I could see most of the Structs are incomplete type and I want to write a function where they are intialized. For example, below code is not working.

int main()
{
   TF_Status* Status = NULL;
   TF_Graph* Graph = NULL;
   init(Status);
   return 0;
}

void init(TF_Status* Status, TF_Graph* Graph)
{
   Status = TF_NewStatus();
   Graph = TF_NewGraph();
}

Any idea how can I do this?

Pass pointers to what to modify to functions to let functions modify them.

void init(TF_Status** Status, TF_Graph** Graph);

int main(void)
{
   TF_Status* Status = NULL;
   TF_Graph* Graph = NULL;
   init(&Status, &Graph);
   return 0;
}

void init(TF_Status** Status, TF_Graph** Graph)
{
   *Status = TF_NewStatus();
   *Graph = TF_NewGraph();
}
