This function should be paired with the MountNtmsMedia function. Syntax C++ DWORD DismountNtmsMedia( __in HANDLE hSession, __in LPNTMS_GUID lpMediaId, __in DWORD dwCount, __in DWORD dwOptions ); Parameters hSession [in] Handle to the session returned by the OpenNtmsSession function. lpMediaId [in] Array of at least one logical medium or side. dwCount [in] Number of media identifiers in the lpMediaId parameter. dwOptions [in] Options. This parameter can be the following value. ValueMeaning NTMS_DISMOUNT_DEFERREDMarks media state as Dismountable, and keeps the medium in the drive. Subsequent mount requests are satisfied using dismounted or dismountable drives. The default is to dismount immediately. NTMS_DISMOUNT_IMMEDIATEDismount the drive immediately. Return Value This function returns one of the following values. ValueMeaning ERROR_ACCESS_DENIEDNTMS_USE_ACCESS to the media pool or library that contains the media 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_AVAILABLEOne or more resources required to perform the dismount are not currently available (probably disabled). ERROR_INVALID_LIBRARYThe library that contains the media is not valid. ERROR_INVALID_MEDIAAt least one of the specified media is not valid. ERROR_INVALID_STATEAn unexpected media or device state occurred during dismount. ERROR_MEDIA_OFFLINEThe specified media is offline. ERROR_MEDIA_NOT_AVAILABLEOne or more media resources required to perform the mount are not currently available (probably disabled). ERROR_NOT_ENOUGH_MEMORYA memory allocation failure occurred during processing. ERROR_SUCCESSThe media dismount has been queued. ERROR_TIMEOUTThe time-out event expired while the application attempted to acquire one or more resources. Remarks An application must use the DismountNtmsMedia function to release the drive resource after the application has used the specified medium. Unreleased media cannot be used by other RSM sessions. The DismountNtmsMedia function returns as soon as the operation is queued with RSM. The application can wait for the side state to become idle.
