The EjectNtmsCleaner function ejects the cleaning cartridge from the currently reserved cleaner slot.

Syntax

DWORD EjectNtmsCleaner(
  __in     HANDLE hSession,
  __in     LPNTMS_GUID lpLibrary,
  __inout  LPNTMS_GUID lpEjectOperation,
  __in     DWORD dwAction
);

Parameters

hSession [in]
Handle to the session returned by the OpenNtmsSession function.
lpLibrary [in]
Unique identifier of a library object.
lpEjectOperation [in, out]
GUID of the eject process library operation. If dwAction is NTMS_EJECT_START, this parameter receives the GUID for the operation. If dwAction is NTMS_EJECT_STOP, this parameter must be set to the GUID for the operation to be stopped.

dwAction [in]
Action to perform. This parameter can be either one of the following values.

Value	Meaning
NTMS_EJECT_START	Starts 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_STOP	For libraries with NTMS_IEPORT objects only. Terminates the ejection process specified by lpEjectOperation prior to the time-out event lapsing.

Return Value

This function returns one of the following values.

Value	Meaning
ERROR_ACCESS_DENIED	Access to one or more RSM objects is denied.
ERROR_INVALID_HANDLE	The value supplied in the hSession parameter is not valid.
ERROR_INVALID_LIBRARY	Unable to retrieve the library definition from the database.
ERROR_NO_SLOT_SET	This library does not have a cleaner slot reserved.
ERROR_NOT_CONNECTED	Unable to connect to the RSM service.
ERROR_SLOT_EMPTY	A cleaner slot is reserved but is already empty.
ERROR_SLOT_NOT_PRESENT	A cleaner slot is reserved but the slot is currently not installed in the library. This error occurs when at least one magazine is missing from the library.
ERROR_SUCCESS	The function was successful.

Remarks

The EjectNtmsCleaner function returns to the application as soon as the eject request is queued.

If the library specified in the EjectNtmsCleaner function has an NTMS_IEPORT object, RSM uses the NTMS_IEPORT object to eject the cleaner. If there is no NTMS_IEPORT object, the NTMS_IEDOOR object is used to allow the operator to gain access to the cleaner slot.

Ejected cleaner cartridges are not tracked in the offline library.
