ID3DXTextureShader::GetConstantDesc method

Gets a pointer to the array of constants in the constant table.

Syntax

HRESULT GetConstantDesc(
  [in]      D3DXHANDLE        hConstant,
  [in, out] D3DXCONSTANT_DESC *pDesc,
  [in, out] UINT              *pCount
);

Parameters

hConstant [in]

Type: D3DXHANDLE

Unique identifier to a constant. See D3DXHANDLE.

pDesc [in, out]

Type: D3DXCONSTANT_DESC*

Returns a pointer to an array of descriptions. See D3DXCONSTANT_DESC.

pCount [in, out]

Type: UINT*

The input supplied must be the maximum size of the array. The output is the number of elements that are filled in the array when the function returns.

Return value

Type: HRESULT

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

Remarks

Samplers can appear more than once in a constant table, therefore, this method can return an array of descriptions each with a different register index.
