I put together the following OutputNotifications() function to show how to enumerate User Notifications.
#include <Notify.h>
void OutputNotifications()
{
HANDLE *hNotifications = NULL;
DWORD NumNotifications;
DWORD Count;
DWORD BytesNeeded;
CE_NOTIFICATION_INFO_HEADER *NIHeader;

// First call CeGetUserNotifications to find out how many notifications are available
// by passing in zero as the second argument
CeGetUserNotificationHandles( hNotifications, 0, &NumNotifications );
RETAILMSG( 1, (TEXT("Num Notifications available %d\n"), NumNotifications ));
hNotifications = (HANDLE *)malloc( NumNotifications * sizeof( HANDLE *) );
// Now get the notifications
CeGetUserNotificationHandles( hNotifications, NumNotifications, &NumNotifications );
for( Count = 0; Count < NumNotifications; Count++ )
{
// Now with a valid handle to a notification find out how many bytes are needed
// to get the data
CeGetUserNotification( hNotifications[Count], 0, &BytesNeeded, NULL );
RETAILMSG( 1, (TEXT("%d Bytes needed %d\n"), Count, BytesNeeded ));
pBuffer = malloc( BytesNeeded );
// Error checking left for you, but now we can get the data
CeGetUserNotification( hNotifications[Count], BytesNeeded, &BytesNeeded, (BYTE *)pBuffer );
