PFND3DDDI_CREATEVERTEXSHADERDECL callback function

The CreateVertexShaderDecl function converts the vertex shader declaration into a hardware-specific format and associates the declaration with a shader handle.

Syntax


PFND3DDDI_CREATEVERTEXSHADERDECL CreateVertexShaderDecl;

__checkReturn HRESULT APIENTRY CreateVertexShaderDecl(
  _In_          HANDLE                           hDevice,
  _Inout_       D3DDDIARG_CREATEVERTEXSHADERDECL *pData,
  _In_    const D3DDDIVERTEXELEMENT              *pVertexElements
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pData [in, out]

A pointer to a D3DDDIARG_CREATEVERTEXSHADERDECL structure that retrieves the shader handle that is associated with the vertex shader declaration that is specified by pVertexElements.

pVertexElements [in]

An array of D3DDDIVERTEXELEMENT structures that make up the vertex shader declaration.

Return value

CreateVertexShaderDecl returns S_OK or an appropriate error result if the vertex shader declaration object is not successfully created.

Remarks

The array of D3DDDIVERTEXELEMENT structures specified by pVertexElements defines vertex data into the pipeline.
