Here we'll describe the user event 137 structure that contains the configuration files used by the ROCs to initialize various modules and settings.

Example User Event 137 Structure

c source code in readout list

 size_t maxsize = 3 * 1024 * 1024;
 int nwords = 0, inum=0;

 UEOPEN(137,BT_BANK,0);

 nwords = rocFile2Event("/daqfs/daq_setups/vtp-mpdro/cfg/davtp3.config",
			 (uint8_t *)rol->dabufp,
			 ROCID, inum++, maxsize);
 rol->dabufp += nwords;
 nwords = rocFile2Event("/daqfs/daq_setups/vtp-mpdro/cfg/pedestals/daq_ped_bb_gem_run10975.dat",
			 (uint8_t *)rol->dabufp,
			 ROCID, inum++, maxsize);
 rol->dabufp += nwords;

 UECLOSE;
