//  Class:  CTransaction (xact)
//
//  Purpose:    Transaction support
//
//  Interface:  CTransaction    - Constructor
//             ~CTransaction    - Destructor
//              GetStatus       - Retrieve status
//              Commit          - Set status to commit
//
//  History:
//              01-Apr-91       KyleP     Created.
//              23-Apr-91       KyleP     Replaced sesid with CSession
//              13-Jan-92       BartoszM  Reversed logic of Commit/Abort
//              16-Jul-92       BartoszM  Removed session
//
//  Notes:      CTransaction objects must be destroyed in the opposite
//              order to their creation.
//              A transaction is created in the aborted state.
//              Unless Commit is explicitely called the destructor
//              will abort the transaction.
