How to return a global array from a function

[[Deleted]]

Dear 

How can I return a global array by a function. Below my code, it give me a error

struct OpenOrders
{
   long   orderId; 
   string symbol; 
   string side; 
};


OpenOrders     _GetOpenOrders[];


void fill_array()
{
  for(int x=0;x<=7000; x++) 
   { 
      if(IsStopped()) break;

       ArrayResize(_GetOpenOrders ,x+1 );
      _GetOpenOrders[x].orderId = (long)_LastResponse_Jason[x]["orderId"].ToStr();
      _GetOpenOrders[x].symbol = _LastResponse_Jason[x]["symbol"].ToStr();
   } 
}


OpenOrders RetrunArray() export
{
  return(_GetOpenOrders);
}

Please anyone correct my code please

You don't need to return a global array because You should be able to access it everywhere.
