Fires after the class unmounts media from the virtual drive, making it unavailable.
class CBFSUnmountEventParams(object): @property def result_code() -> int: ... @result_code.setter def result_code(value) -> None: ... # In class CBFS: @property def on_unmount() -> Callable[[CBFSUnmountEventParams], None]: ... @on_unmount.setter def on_unmount(event_hook: Callable[[CBFSUnmountEventParams], None]) -> None: ...
This event is optional; it is provided to give applications a chance to perform additional processing when the virtual filesystem becomes unavailable.
The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
