Dealing with the driver->interrupt() Call

When your MUD's driver object receives a call to interrupt() from DGD, it means the server has received a kill signal. Normally, that means you'll want to force all users to quit, dump any appropriate state, and call shutdown(). You may also want to write to a log file or set up an error message to let somebody know that the MUD has received an error or kill signal and shut down.

Note that shutdown() will not take effect until the end of the thread in which you call it. If shutdown() is not called within interrupt, DGD will not shut down. So you can start a timer or other shutdown sequence if necessary.
