 ***************************************************************************
 * Description: TPC reader for raw cluster pointer banks (TPCCPPR)
 *      
 *
 *   change log
 * 06-May-99 MJL code cloned from Jeff's ADCR_SR
 * 22-Jun-99 MJL added TPCV2P0_CPP_SR::getAsicParams(struct ASIC_params *);
 * 29-Aug-99 MJL #include <Stiostream.h> for HP platform
 * 03-Feb-00 MJL print ASCI params so PT Barnum's clientele can grock them
 *
 ***************************************************************************
 * $Log: TPCV2P0_CPP_SR.cxx,v $
 * Revision 1.8  2007/12/24 06:04:32  fine
 * introduce OLDEVP namespace to allow ole and new EVP library concurrently
 *
 * Revision 1.7  2003/09/02 17:55:33  perev
 * gcc 3.2 updates + WarnOff
 *
 * Revision 1.6  2000/02/03 21:18:36  levine
 * change printout of ASIC parameters to idiot-proof mode
 *
 * Revision 1.5  2000/01/04 20:55:04  levine
 * Implemented memory-mapped file access in EventReader.cxx. Old method
 * (via seeks) is still possible by setting mmapp=0 in
 *
 *      getEventReader(fd,offset,(const char *)logfile,mmapp);
 *
 *
 * but memory-mapped access is much more effective.
 *
 * Revision 1.4  1999/09/02 21:47:12  fisyak
 * HP corrections
 *
 * Revision 1.3  1999/07/02 04:43:24  levine
 * Many changes -
 *  navigates to head of TPCP bank independent of position.
 *  move declarations out of loops where they were upsetting some compilers
 *  suppress output from class libraries with run-time switch EventReader.verbose
 *  added TPCV2P0_CPP_SR::getAsicParams()
 *
