The IMDSPStorageGlobals interface provides methods for accessing global information about the medium regardless of the nesting level of the IMDSPStorage interface from which the global view is accessed. Any instance of IMDSPStorage can acquire an IMDSPStorageGlobals interface.

This method must be implemented. It must not return WMDM_E_NOTSUPPORTED or E_NOTIMPL. For more information, see Mandatory and Optional Interfaces.
