DXGKMDT_CERTIFICATE_TYPE enumeration

Description

The DXGKMDT_CERTIFICATE_TYPE enumeration identifies the type of certificate that callers of the DxgkDdiOPMGetCertificateSize and DxgkDdiOPMGetCertificate functions require.

Constants

`DXGKMDT_OPM_CERTIFICATE`

Indicates an Output Protection Management (OPM) certificate.

`DXGKMDT_COPP_CERTIFICATE`

Indicates a Certified Output Protection Protocol (COPP) certificate.

`DXGKMDT_UAB_CERTIFICATE`

Indicates a User Accessible Bus (UAB) certificate.

`DXGKMDT_INDIRECT_DISPLAY_CERTIFICATE`

`DXGKMDT_FORCE_ULONG`

Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. You should not use this value.

Remarks

For more information about certificates that are used with OPM, download the Output Content Protection and Windows Vista document.
