Important

This function is used by Output Protection Manager (OPM) to access functionality in the display driver. Applications should not call this function.

 

Sends a Certified Output Protection Protocol (COPP) status request to a protected output object.

  _In_  OPM_PROTECTED_OUTPUT_HANDLE                     opoOPMProtectedOutput,
  _In_  DXGKMDT_OPM_COPP_COMPATIBLE_GET_INFO_PARAMETERS *pParameters,
  _Out_ DXGKMDT_OPM_REQUESTED_INFORMATION               *pRequestedInformation
);

Parameters

opoOPMProtectedOutput [in]

A handle to the protected output object. This handle is obtained by calling CreateOPMProtectedOutputs.

pParameters [in]

pRequestedInformation [out]

A pointer to a DXGKMDT_OPM_REQUESTED_INFORMATION structure that receives the results of the status request.
