I have followed your suggestions and my code now runs like this:
TFile *fFile = new TFile("somefilename");
TTree *fTree = (TTree*) fFile->Get("EventsTree");
TBranch *b_Events=fTree->GetBranch("Event");
THenaEvent *fRaw = 0; //THenaEvent is a custom class written for
holding data
b_Events->SetAddress(&fRaw);
b_Events->GetEntry(anything);
delete fFile;
And this works fine so far. However when I now try to read another file,
after executing the above macro, by typing
fFile = new TFile("someotherfilename");
fFile = new TFile("somefilename");
b_Events=fTree->GetBranch("Event");
fRaw=0;
b_Events->SetAddress(&fRaw);
I have no problem calling
b_Events->GetEntries()
but calling
b_Events->GetEntry(42)
results again in a segmentation fault.
Any suggestions?
