ID3DXBaseEffect::GetValue method

Get the value of an arbitrary parameter or annotation, including simple types, structs, arrays, strings, shaders and textures. This method can be used in place of nearly all the Getxxx calls in ID3DXBaseEffect.

Syntax

HRESULT GetValue(
  [in]  D3DXHANDLE hParameter,
  [out] LPVOID     pData,
  [in]  UINT       Bytes
);

Parameters

hParameter [in]

Type: D3DXHANDLE

Unique identifier. See Handles (Direct3D 9).

pData [out]

Type: LPVOID

Returns a buffer containing the value.

Bytes [in]

Type: UINT

[in] Number of bytes in the buffer. Pass in D3DX_DEFAULT if you know your buffer is large enough to contain the entire parameter, and you want to skip size validation.

Return value

If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be D3DERR_INVALIDCALL.
