V559. Suspicious assignment inside the conditional expression of 'if/while/for' statement.

V559 Suspicious assignment inside the condition expression of 'if' operator: ret = 0. clist_mw clcidents.c 179


int FindItem(....)
{
  ....
  int ret;
  ret=FindItem(hwnd,dat,hItem,
               (struct ClcContact ** )&z,
               (struct  ClcGroup** )&isv,NULL);
  if (ret=0) {return (0);}
  ....
}

This is what should have been written here: if (ret==0) {return (0);}
