IddCxMonitorGetSrmListVersion function (iddcx.h)

IddCxMonitorGetSrmListVersion retrieves the latest System Renewability Message (SRM) list version stored by the GPU.

Syntax

NTSTATUS IddCxMonitorGetSrmListVersion(
  [in]  IDDCX_MONITOR                    MonitorObject,
  [in]  const IDARG_IN_GETSRMLISTVERSION *pInArgs,
  [out] IDARG_OUT_GETSRMLISTVERSION      *pOutArgs
);

Parameters

[in] MonitorObject

The IDDCX_MONITOR object that the SRM list is associated with.

[in] pInArgs

Pointer to an IDARG_IN_GETSRMLISTVERSION structure with input parameters.

[out] pOutArgs

Pointer to an IDARG_OUT_GETSRMLISTVERSION structure in which the OS returns output.

Return value

If the routine succeeds it returns STATUS_SUCCESS; otherwise it returns an appropriate error code such as one of the following:

Error code Meaning
STATUS_GRAPHICS_OPM_NOT_SUPPORTED The GPU driver does not support this functionality.
STATUS_NO_DATA_DETECTED The GPU does not have a current SRM list.
STATUS_BUFFER_TOO_SMALL The buffer that pOutArgs points to is too small.

Remarks

An indirect display driver (IDD) calls IddCxMonitorGetSrmListVersion to retrieve the latest SRM list version stored by the GPU. To set an SRM list, call IddCxMonitorSetSrmList.

SRMs are used to update the list of revoked High-Bandwidth Digital Content Protection (HDCP) devices, and are delivered with the video content.
