PFND3DDDI_DESTROYAUTHENTICATEDCHANNEL callback function

Description

The DestroyAuthenticatedChannel function releases resources for the authenticated channel that the CreateAuthenticatedChannel function creates.

Parameters

`hDevice`

A handle to the display device (graphics context).

`unnamedParam2`

pData [in]

A pointer to a D3DDDIARG_DESTROYAUTHENTICATEDCHANNEL structure that contains one member that specifies the handle to the authenticated channel to destroy.

Return value

DestroyAuthenticatedChannel returns one of the following values:

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).
