5 | This program connects to the DAQ data source passed as argument | |
6 | and populates local "./result.txt" file with the ids of events received | |
7 | during the run. | |
8 | ||
9 | The program exits when being asked to shut down (daqDA_checkshutdown) | |
10 | or End of Run event. | |
11 | ||
12 | Messages on stdout are exported to DAQ log system. | |
