D3DXAssembleShaderFromFile function

Assemble a shader.

Syntax

HRESULT D3DXAssembleShaderFromFile(
  _In_        LPCTSTR       pSrcFile,
  _In_  const D3DXMACRO     *pDefines,
  _In_        LPD3DXINCLUDE pInclude,
  _In_        DWORD         Flags,
  _Out_       LPD3DXBUFFER  *ppShader,
  _Out_       LPD3DXBUFFER  *ppErrorMsgs
);

Parameters

pSrcFile [in]

Type: LPCTSTR

Pointer to a string that specifies the filename. If the compiler settings require Unicode, the data type LPCTSTR resolves to LPCWSTR. Otherwise, the string data type resolves to LPCSTR. See Remarks.

pDefines [in]

Type: const D3DXMACRO*

An optional NULL terminated array of D3DXMACRO structures. This value may be NULL.

pInclude [in]

Type: LPD3DXINCLUDE

Optional interface pointer, ID3DXInclude, to use for handling #include directives. If this value is NULL, #includes will either be honored when compiling from a file or will cause an error when compiled from a resource or memory.

Flags [in]

Type: DWORD

Compile options identified by various flags. The Direct3D 10 HLSL compiler is now the default. See D3DXSHADER Flags for details.

ppShader [out]

Type: LPD3DXBUFFER*

Returns a buffer containing the created shader. This buffer contains the compiled shader code, as well as any embedded debug and symbol table information.

ppErrorMsgs [out]

Type: LPD3DXBUFFER*

Returns a buffer containing a listing of errors and warnings that were encountered during the compile. These are the same messages the debugger displays when running in debug mode. This value may be NULL.

Return value

Type: HRESULT

If the function succeeds, the return value is D3D_OK. If the function fails, the return value can be one of the following: D3DERR_INVALIDCALL, D3DXERR_INVALIDDATA, E_OUTOFMEMORY.

Remarks

The compiler setting also determines the function version. If Unicode is defined, the function call resolves to D3DXAssembleShaderFromFileW. Otherwise, the function call resolves to D3DXAssembleShaderFromFileA because ANSI strings are being used.
