ID3D10Include::Open method

A user-implemented method for opening and reading the contents of a shader #include file.

Syntax

HRESULT Open(
  [in]  D3D10_INCLUDE_TYPE IncludeType,
  [in]  LPCSTR             pFileName,
  [in]  LPCVOID            pParentData,
  [out] LPCVOID            *ppData,
  [in]  UINT               *pBytes
);

Parameters

IncludeType [in]
Type: D3D10_INCLUDE_TYPE

The location of the #include file. See D3D10_INCLUDE_TYPE.
pFileName [in]
Type: LPCSTR

Name of the #include file.
pParentData [in]
Type: LPCVOID

Pointer to the container that includes the #include file. The compiler might pass NULL in pParentData. For more information, see the "Searching for Include Files" section in Compile an Effect (Direct3D 11).
ppData [out]
Type: LPCVOID*

Pointer to the returned buffer that contains the include directives. This pointer remains valid until ID3D10Include::Close is called.
pBytes [in]
Type: UINT*

Number of bytes returned in ppData.

Return value

Type: HRESULT

The user-implemented method should return S_OK. If the callback fails when reading the #include file, the application programming interface (API) that caused the callback to be called will fail. This is one of the following:

The high-level shader language (HLSL) shader will fail one of the D3D10CompileShader*** functions.
The effect will fail one of the D3D10CreateEffect*** functions.

Remarks

The ID3D10Include interface is type defined in the D3D10Shader.h header file as a ID3DInclude interface, which is fully defined in the D3DCommon.h header file.

typedef interface ID3DInclude ID3D10Include;
