Hi, See the implementation of TChain::Add(const char *name, Int_t nentries) (http://root.cern.ch/root/html/src/TChain.cxx.html#TChain:Add) for an example. Cheers, Philippe -----Original Message----- From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch]On Behalf Of Raquel de los Reyes Sent: Friday, March 26, 2004 10:53 AM To: Roottalk Subject: [ROOT] Sorting the directory content Hi roorters, I have found in the Root Search web page, a small macro to list the directory files: void *dirp = gSystem->OpenDirectory(directory); const char *afile; while(afile = gSystem->GetDirEntry(dirp)) { printf("file: %s\n",afile); } My problem is that the showed list of files is not sorted (equivalent Unix comand: "ls -f"), neither alphabetically nor chronological order. How could I display the directory content in alphabetical or chronogical order?. Thank you in advance.
