William, 

This is without testing, but I think it works like this:

  GDALDatasetH *paphList;
  int nCount, i;

  GDALGetOpenDatasets( &paphList, &nCount );

  for( i = 0; i < nCount; i++ )
  {
      GDALDatasetH hDS = paphList[i];

      printf( "dataset name = %s\n", 
                GDALGetDescription( hDS ) );      
  }

Best regards,
