Return code	Description
S_OK	The authenticated channel is successfully destroyed.
E_OUTOFMEMORY	DestroyAuthenticatedChannel could not allocate the required memory for it to complete.

Remarks

The driver's DestroyAuthenticatedChannel function should disable any protections that were set through calls to the driver's ConfigureAuthenticatedChannel function with the D3DAUTHETICATEDCONFIGURE_PROTECTION and D3DAUTHENTICATEDCONFIGURE_ENCRYPTIONWHENACCESIBLE GUIDs set. However, the driver should not disable shared surface protection (D3DAUTHETICATEDCONFIGURE_SHAREDRESOURCE).
