Re: checking result of SetBranchAddress

Hi Alexander,

The example you sent:

   printf("--> %s before %p\n", branchName, tree->GetBranch(branchName)); //

prints the location of the branch object itself and __not__ the location of the user object the branch will use to fill in or read from the TTree. The location of the branch object is, of course, not affected by the call to SetBranchAddres. You ought to use

   printf("--> %s before %p\n", branchName, tree->GetBranch(branchName)->GetAddress()); //

Cheers,
Philippe.
