Syntax

HRESULT EnumerateMetaCommandParameters(
  [in]            REFGUID                            CommandId,
  [in]            D3D12_META_COMMAND_PARAMETER_STAGE Stage,
  [out, optional] UINT                               *pTotalStructureSizeInBytes,
  [in, out]       UINT                               *pParameterCount,
  [out, optional] D3D12_META_COMMAND_PARAMETER_DESC  *pParameterDescs
);

Parameters

[in] CommandId

Type: REFIID

A reference to the globally unique identifier (GUID) of the meta command whose parameters you wish to be returned in pParameterDescs.

[in] Stage

Type: D3D12_META_COMMAND_PARAMETER_STAGE

A D3D12_META_COMMAND_PARAMETER_STAGE specifying the stage of the parameters that you wish to be included in the query.

[out, optional] pTotalStructureSizeInBytes

Type: UINT*

An optional pointer to a UINT containing the size of the structure containing the parameter values, which you pass when creating/initializing/executing the meta command, as appropriate.

[in, out] pParameterCount

Type: UINT*

A pointer to a UINT containing the number of parameters to query for. This field determines the size of the pParameterDescs array, unless pParameterDescs is nullptr.

[out, optional] pParameterDescs

Type: D3D12_META_COMMAND_PARAMETER_DESC*

An optional pointer to an array of D3D12_META_COMMAND_PARAMETER_DESC containing the descriptions of the parameters. Pass nullptr to have the parameter count returned in pParameterCount.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
