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. |
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.
