  • Article

Retrieves the requested PSO from the library.

Syntax

HRESULT LoadGraphicsPipeline(
  [in]  LPCWSTR                                  pName,
  [in]  const D3D12_GRAPHICS_PIPELINE_STATE_DESC *pDesc,
        REFIID                                   riid,
  [out] void                                     **ppPipelineState
);

Parameters

[in] pName

Type: LPCWSTR

The unique name of the PSO.

[in] pDesc

Type: const D3D12_GRAPHICS_PIPELINE_STATE_DESC*

Specifies a description of the required PSO in a D3D12_GRAPHICS_PIPELINE_STATE_DESC structure. This input description is matched against the data in the current library database, and stored in order to prevent duplication of PSO contents.

riid

Type: REFIID

Specifies a REFIID for the ID3D12PipelineState object. Typically set this, and the following parameter, with the macro IID_PPV_ARGS(&PSO1), where PSO1 is the name of the object.

[out] ppPipelineState

Type: void**

Specifies a pointer that will reference the returned PSO.

Return value

Type: HRESULT

This method returns an HRESULT success or error code, which can include E_INVALIDARG if the name doesn’t exist, or if the input description doesn’t match the data in the library, and E_OUTOFMEMORY if unable to allocate the return PSO.
