Open files in a directory with a for loop

ROOT

Hi Ian,

Here is a simple example showing how to list files in a directory:

void list_files(const char *dirname="C:/root/folder/", const char *ext=".root")
{
   TSystemDirectory dir(dirname, dirname);
   TList *files = dir.GetListOfFiles();
   if (files) {
      TSystemFile *file;
      TString fname;
      TIter next(files);
      while ((file=(TSystemFile*)next())) {
         fname = file->GetName();
         if (!file->IsDirectory() && fname.EndsWith(ext)) {
            cout << fname.Data() << endl;
         }
      }
   }
}

Hope this will help…

Cheers, Bertrand.
