try this : 

function sample_user_login(&$edit, $account){
  if(function_exists('callType'){
     callType();
  }else{
    die('Function callType does not declared');
  }
}

You must to know , drupal hook implementation is in cache so , on every modification made you have to clear registry cache

Try this.

function sample_user_login(&$edit, $account){
 $anivpopup = '1';
 callType($anivpopup);
}

function callType($anivpopup){
 if($anivpopup == '1'){
     setcookie('test', '2', time()+3600);  //cookie set for 1 hr
 }
}

Hope this helps you.
