PFN_IDDCXMONITORGETSRMLISTVERSION is a pointer to an OS callback function that retrieves the latest System Renewability Message (SRM) list version stored by the GPU.

Syntax

PFN_IDDCXMONITORGETSRMLISTVERSION PfnIddcxmonitorgetsrmlistversion;

NTSTATUS * PfnIddcxmonitorgetsrmlistversion(
  [in]  PIDD_DRIVER_GLOBALS DriverGlobals,
  [in]  IDDCX_MONITOR MonitorObject,
  [in]  const IDARG_IN_GETSRMLISTVERSION *pInArgs,
  [out] IDARG_OUT_GETSRMLISTVERSION *pOutArgs
)
{...}

Parameters

[in] DriverGlobals

Contains system-defined per-driver data.

[in] MonitorObject

The monitor object that the SRM list is associated with.

[in] pInArgs

Input arguments of the function.

[out] pOutArgs

Output arguments of function.

Return value

Returns NTSTATUS with the following error codes:

Return value Description
STATUS_SUCCESS The routine succeeded.
STATUS_GRAPHICS_OPM_NOT_SUPPORTED The GPU driver does not support this new functionality.
STATUS_NO_DATA_DETECTED The GPU does not have a current SRM list.
STATUS_BUFFER_TOO_SMALL The passed in buffer is too small.
