// The way to use CPassportException
//
//      throw CPassportException(__FILE__, __LINE__, hr, long1, long2, long3)
//
//  1.  don't ever pass anything other than __FILE__, __LINE__ as the first two
//      argument.
//  2.  You may pass some description through compilatime time string
//      concatenation as __FILE__";description".   Make sure ";" is the first
//      character after __FILE__.   
//      A separate description argument is explicit avoided so that
//          a) CPassportException doesn't have to alloc another copy of string.
//          b) or have to worry about freeing things.
//          c) to keep CPassportException very small in size.
//
