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

-
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.
