on_ejected Event
Fires when the media and virtual drive have been ejected.
Syntax
class CBFSEjectedEventParams(object): @property def result_code() -> int: ... @result_code.setter def result_code(value) -> None: ... # In class CBFS: @property def on_ejected() -> Callable[[CBFSEjectedEventParams], None]: ... @on_ejected.setter def on_ejected(event_hook: Callable[[CBFSEjectedEventParams], None]) -> None: ...
Remarks
This event fires when a user has ejected the media and virtual drive using the Eject command in Windows Explorer.
For ejection via the system notification area (tray) to work correctly, the storage_type property must be set to STGT_DISK_PNP, and the storage_characteristics property must include ejection-related flags.
This event is optional; it is provided to give applications a chance to, e.g., free up resources associated with the virtual drive. Since the virtual drive has already been destroyed by the time this event fires, applications must not call unmount_media or delete_storage (the latter is called automatically with its ForceUnmount parameter set to True) .
The ResultCode parameter will always be set to the result code returned by the automatic call to delete_storage. 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.
