_D3DDDIARG_ENCRYPTIONBLT structure

Description

The D3DDDIARG_ENCRYPTIONBLT structure describes the parameters of an encrypted bit-block transfer (bitblt) in a call to the EncryptionBlt function.

Members

hCryptoSession [in]

A handle to the encryption session.

hSrcResource [in]

A handle to the source resource.

SrcSubResourceIndex [in]

The index to the source surface within the resource.

hDstResource [in]

A handle to the destination resource.

DstSubResourceIndex [in]

The index to the destination surface within the resource.

DstResourceSize [in]

The size, in bytes, of the destination resource.

pIV [out]

A pointer to a block of memory in which EncryptionBlt returns the initialization vector that is required to decrypt the bitblt data. If pIV is NULL, hardware does not require a separate key to decrypt the data that is read back.
