Syntax C++ DWORD EjectDiskFromSADrive( __in LPCWSTR lpComputerName, __in LPCWSTR lpAppName, __in LPCWSTR lpDeviceName, __in HWND hWnd, __in LPCWSTR lpTitle, __in LPCWSTR lpMessage, __in DWORD dwOptions ); Parameters lpComputerName [in] Removable Storage Manager (RSM) server name. If this parameter is NULL, the current computer name is used. lpAppName [in] Unique character string that identifies the application. This name identifies resources and operator requests. This parameter is optional and may be NULL. lpDeviceName [in] Name of the device to eject. For example, \\\\.\\Cdrom0 or \\\\.\\PhysicalDriveX (where X is the number of the drive being accessed). hWnd [in] Handle to a dialog box window for user confirmation. lpTitle [in] Title displayed in a dialog box to get user input. lpMessage [in] Message displayed in a dialog box to get user input. dwOptions [in] Action to perform. This parameter can be one of the following values. ValueMeaning NTMS_EJECT_STARTStart the eject operation with a port. The specified medium is ejected until the time-out event occurs or the function is called again with NTMS_EJECT_STOP. The time-out value is specified in the library object and is applied to all ejections in the library. NTMS_EJECT_STOPTerminate the ejection process before the time-out event lapses. NTMS_EJECT_QUEUEAllow the eject to be asynchronous. The function queues the specified media for ejection and then returns. NTMS_EJECT_FORCEForce the media to be ejected. For example, NTFS can hold locks on media, and this option will cause the media to be ejected despite that lock. NTMS_EJECT_IMMEDIATEEject the media immediately and synchronously. The function will not return until the eject is complete. Does not queue the specified media for ejection. NTMS_EJECT_ASK_USEREject the media immediately and synchronously. The function will not return until the eject is complete. Does not queue the specified media for ejection. If the eject operation fails, prompt the user to either cancel or force the operation. Return Value This function returns one of the following values. ValueMeaning ERROR_ACCESS_DENIEDNTMS_CONTROL_ACCESS to the library is denied. Other security errors are also possible, but they would indicate a security subsystem error. ERROR_DATABASE_FAILUREThe database is inaccessible or damaged. ERROR_DATABASE_FULLThe database is full. ERROR_DEVICE_NOT_AVAILABLEThe library is disabled. ERROR_INVALID_HANDLEThe session ID is missing or is not valid. ERROR_INVALID_OPERATIONA stop was performed on an operation ID that was not valid. ERROR_INVALID_PARAMETERA library ID or operation ID pointer is missing. ERROR_LIBRARY_OFFLINEThe library ID refers to an offline library that cannot eject media. ERROR_MEDIA_NOT_AVAILABLEThe media is disabled. ERROR_NOT_ENOUGH_MEMORYThere was an allocation failure during processing. ERROR_SUCCESSThe eject operation was successful. Remarks Although EjectNtmsMedia can, in some cases, be used to accomplish the same functionality, EjectDiskFromSADrive provides a convenient way to eject media from a standalone device, by specifying its drive name instead of its RSM name. In some cases it is the only way to overcome file system locks on the media in order to eject that media. The EjectDiskFromSADrive function returns to the application as soon as the eject request is queued, unless NTMS_EJECT_IMMEDIATE option is specified. Media ejected using the EjectDiskFromSADrive function is moved to the offline library or deleted from the database. Import media, unrecognized media, and incompatible media are deleted when ejected. The EjectDiskFromSADrive function does not work with the offline library.
