D3DXPreprocessShaderFromResource

Preprocesses a shader resource without performing compilation. This resolves all #defines and #includes, providing a self-contained shader for subsequent compilation.

HRESULT D3DXPreprocessShaderFromResource(
  HMODULE hSrcModule,
  LPCSTR pSrcResource,
  CONST D3DXMACRO* pDefines,
  LPD3DXINCLUDE pInclude,
  LPD3DXBUFFER* ppShaderText,
  LPD3DXBUFFER* ppErrorMsgs
);

Parameters

hSrcModule

[in] Handle to the module that holds the shader resource. If this value is NULL, the current module will be used.

pSrcResource

[in] String that represents the name of the resource in the module.

pDefines

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

pInclude

[in] 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.

ppShaderText

[out] Returns a buffer containing a single large string that represents the resulting formatted token stream.

ppErrorMsgs

[out] 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 Values

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.

Requirements

Header: Declared in D3dx9shader.h.
