String passing between functions in VC++ SDI application

[VictorN]

Void sendtext(CString str)
{
   // do some operations
................
  pView->displaytext(str);
}
 
void displaytext(CString inr)
{
  CListCtrl &ctlsde = this->GetListCtrl();
  ctlsde.InsertColumn(1,  _T("First "),   LVCFMT_LEFT,   80);
 
  int nItem;
	nItem = ctlsde.InsertItem(0,  inr);
}

1. Better way to pass CString into a function is by const reference, not by value! Like

   void sendtext(const CString& str)
   ...
   void displaytext(const CString& inr)

2. What is pView?
3. Is your displaytext a global function? Then what is this pointer within it?
