I see from your replies what you're trying to say. If an error occurs, most likely you want the entire operation to abort -- that doesn't necessarily mean the whole program depending on the program.
For example, if I have a GUI app and the "save" operation fails and I typically roll that back right to the event loop of the application and the user gets an error and they can retry the save.
For other types of applications, killing the whole process is ending the operation.
