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_GRAPHICS_OPM_INVALID_SRM | The GPU driver does not recognize the format of the SRM list. This includes whether the driver detected the list had been tampered with. |
An indirect display driver (IDD) calls IddCxMonitorGetSrmList to pass a High-Bandwidth Digital Content Protection (HDCP) SRM list to the GPU driver associated with the rendering of the specified monitor. To get the SRM list version, call IddCxMonitorGetSrmListVersion.
SRMs are used to update the list of revoked High-Bandwidth Digital Content Protection (HDCP) devices, and are delivered with the video content.
