[Removable Storage Manager is no longer available as of Windows 7 and Windows Server 2008 R2.]

The DeleteNtmsMediaType function deletes the specified media type relation from the specified library, provided that the library does not contain any physical media objects of the specified media type.

Syntax

DWORD DeleteNtmsMediaType(
  __in  HANDLE hSession,
  __in  LPNTMS_GUID lpMediaTypeId,
  __in  LPNTMS_GUID lpLibId
);

Parameters

hSession [in]
Handle to the session returned by the OpenNtmsSession function.
lpMediaTypeId [in]
Unique identifier of a media type to delete from a library.
lpLibId [in]
Unique identifier of the library from which to delete the media type.

Return Value

This function returns one of the following values.

Value	Meaning
ERROR_ACCESS_DENIED	NTMS_MODIFY_ACCESS to the library is denied. Other security errors are possible, but indicate a security subsystem error. Windows XP/2000: NTMS_CONTROL_ACCESS to the library is denied. Other security errors are possible, but indicate a security subsystem error.
ERROR_DATABASE_FAILURE	The database is inaccessible or damaged.
ERROR_DATABASE_FULL	The database is full.
ERROR_INVALID_HANDLE	The session handle is missing or is not valid.
ERROR_INVALID_LIBRARY	The library ID is not valid.
ERROR_INVALID_PARAMETER	The media type or library ID is missing.
ERROR_NOT_ENOUGH_MEMORY	An allocation failure occurred during processing.

Remarks

If there are no physical media objects of the specified media type in the RSM system and there are no library objects that contain the specified media type relation in the RSM system, the system media pools for that media type will be deleted. Inability to delete the system media pools does not cause the DeleteNtmsMediaType function to fail.
