Unmount Event
Fires after the class unmounts media from the virtual drive, making it unavailable.
Syntax
class CBFSUnmountEventParams { public: int ResultCode(); void SetResultCode(int iResultCode); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Unmount(CBFSUnmountEventParams *e);
// Or, subclass CBFS and override this emitter function. virtual int FireUnmount(CBFSUnmountEventParams *e) {...}
Remarks
This event fires once the class has unmounted media from the virtual drive, making it unavailable. Please refer to UnmountMedia and DeleteStorage for more information.
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.
