PFND3D11_1DDI_CALCPRIVATECRYPTOSESSIONSIZE callback function

-description

Returns the number of bytes that the driver requires to store private data for the cryptographic session state.

-parameters

-param hDevice

A handle to the display device (graphics context).

-param pCreateData

A pointer to a D3D11_1DDIARG_CREATECRYPTOSESSION structure that describes the cryptographic session.

-returns

The required number of bytes for the cryptographic session state.

-remarks

The runtime will validate the members of the D3D11_1DDIARG_CREATECRYPTOSESSION structure before it calls this function.

This function is not expected to fail.
