Using Xrootd from ROOT

Reading or writing files within ROOT requires the class TXNetFile which is found in the library libNetx.so.
This library is loaded automatically if the static method TFlle::Open() is used to open the file.

       root [2] TFile *f = TFile::Open("root://glast-rdr//wilko/test/basic.root")     // Reading a file

If  TXnetFile is used directly the library has to be loaded first:

       root[2]  .L $ROOTSYS/libNetx.so
       root[3]  TFile *f = new TXNetFile("root://glast-rdr//wilko/test/basic.root", ,"RECREATE"))    // Open a file for writing
