DDIAUTHENTICATEDCHANNELTYPE enumeration (d3dumddi.h)

  • Article

The DDIAUTHENTICATEDCHANNELTYPE enumeration contains values that identify authenticated-channel types.

Syntax

typedef enum _DDIAUTHENTICATEDCHANNELTYPE {
  DDIAUTHENTICATEDCHANNEL_DRIVER_SOFTWARE,
  DDIAUTHENTICATEDCHANNEL_DRIVER_HARDWARE
} DDIAUTHENTICATEDCHANNELTYPE;

Constants

 
DDIAUTHENTICATEDCHANNEL_DRIVER_SOFTWARE
The value specifies that the authenticated-channel type is software.
DDIAUTHENTICATEDCHANNEL_DRIVER_HARDWARE
The value specifies that the authenticated-channel type is hardware.

Remarks

The user-mode display driver receives a DDIAUTHENTICATEDCHANNELTYPE-typed value in the ChannelType member of the DDICERTIFICATEINFO structure. The pInfo member of the D3DDDIARG_GETCAPS structure points to this DDICERTIFICATEINFO structure when the driver's GetCaps function is called with the D3DDDICAPS_GETCERTIFICATE value set in the Type member of D3DDDIARG_GETCAPS.

The Microsoft Direct3D runtime specifies a DDIAUTHENTICATEDCHANNELTYPE-typed value in the ChannelType member of the D3DDDIARG_CREATEAUTHENTICATEDCHANNEL structure that the pData parameter points to in a call to the driver's CreateAuthenticatedChannel function.
