ID3DXFragmentLinker::LinkVertexShader Method


Link a compiled vertex shader at run time. This is a very lightweight operation.

Syntax

HRESULT LinkVertexShader(      

    LPCSTR pProfile,     DWORD Flags,     CONST D3DXHANDLE *rgFragmentHandles,     UINT cFragments,     LPDIRECT3DVERTEXSHADER9* pVShader,     LPD3DXBUFFER *ppErrorMsgs );

Parameters

pProfile
[in] Pointer to a vertex shader profile which detemines the shader instruction set. See D3DXGetVertexShaderProfile for a list of the profiles available.
Flags
[in] Link options. See D3DXSHADER Compile Options.
rgFragmentHandles
[in] An array of vertex shader fragment handles. See Handles.
cFragments
[in] Number of fragments to be linked.
pVShader
[out] Pointer to a vertex shader. See IDirect3DVertexShader9.
ppErrorMsgs
[out, retval] Buffer containing at least the first compile error message that occurred. This includes effect compiler errors and high-level language compile errors. For more information about accessing the buffer, see ID3DXBuffer.

Return Value

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be one of the following:

E_FAILAn undetermined error occurred inside the Microsoft Direct3D subsystem.
D3DERR_INVALIDCALLThe method call is invalid. For example, a method's parameter may have an invalid value.
D3DXERR_INVALIDDATAThe data is invalid.
E_OUTOFMEMORYDirect3D could not allocate sufficient memory to complete the call.
