StCloseFileOnTerminate Class Reference
Class
StCloseFileOnTerminate - it is a singleton to catch the SIGTERM signal (sent by Condor for example) to close all open ROOT files. To activate, insert into your code:
StCloseFileOnTerminate::Instantiate(); On kill <PID> the Notify method is to close all existing ROOT files and terminated the applcation. It is simple. However it is error-prone. The signal SIGTERM can be emitted at the time of I/O operation. As result this I/O operation can not be completed and no way the file can be close properly.
