Queries reflection metadata about the parameters of the specified meta command.

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.
