Fix for 64-bit platforms

[u/mrichter/AliRoot.git] / TRD / TRDda.cxx

/*


TRDda.cxx - calibration algorithm to be run on monitoring server
DAcase2.c

AliTRDCalibraFillHisto - average pulse height/ vdrift calibration
AliTRDCalibPadStatus - pad status calibration


This program connects to the DAQ data source passed as argument
and populates local "./result.txt" file with the ids of events received
during the run.

The program exits when being asked to shut down (daqDA_checkshutdown)
or End of Run event.

Messages on stdout are exported to DAQ log system.
