  • Article

Contains input data for the ID3D11VideoContext::ConfigureAuthenticatedChannel method.

Syntax

typedef struct D3D11_AUTHENTICATED_CONFIGURE_INPUT {
  D3D11_OMAC omac;
  GUID       ConfigureType;
  HANDLE     hChannel;
  UINT       SequenceNumber;
} D3D11_AUTHENTICATED_CONFIGURE_INPUT;

Members

omac

A D3D11_OMAC structure that contains a Message Authentication Code (MAC) of the data. The driver uses AES-based one-key CBC MAC (OMAC) to calculate this value for the block of data that appears after this structure member.

ConfigureType

A GUID that specifies the command. The following GUIDs are defined.
