Hi root team, Sometimes we need to read a file that was left open by an aborted write job. In this case the file is not properly closed, and on read of the file the TFile::Recover method will attempt to rebuild the key directory for the file. If the TFile::Recover method fails to recover any keys for the file it prints the warning message: "no keys recovered" for the file, but I can't seem to find a way to determine at run time that in this case the file is unreadable. The TFile methods IsZombie() and IsOpen() both indicate after TFile construction that the file is open and ready to be read. This causes my code to go ahead and attempt to read the set of keys from the file (TDirectory::ReadKeys returns a non-null number of keys) and use the keys, eventually resulting in a segv. Is it possible to determine at run-time that the file was not recoverable? I am using cvs root last updated on 1/22/02. -Sue
