Function Documentation

handle_signal()

void engine::handle_signal ( int  sig )

inline

Handle interrupt signals sent by the operating system.

When this function is called, it cannot call any other functions that might have set any locks, because it might not get the lock, and then the program hangs instead of gracefully exiting. It's a bit sad, true, but that's the way it is.

That is why you cannot make use of the logging in this function. You also cannot make use of triggers, because they also have a lock.

The function immediately resets the signal handler to the default provided by the standard library, so that in the case that we do hang for some reasons, the user can force abort by sending the signal a third time.
