Loads into memory a compressed precomputed radiance transfer (PRT) buffer that was saved to disk.

Syntax

HRESULT D3DXLoadPRTCompBufferFromFile(
  _In_    LPCSTR              pFileName,
  _Inout_ LPD3DXPRTCOMPBUFFER *ppBuffer
);

Parameters

pFileName [in]

Type: LPCSTR

Name of the file from which to load the compressed buffer data.

ppBuffer [in, out]

Type: LPD3DXPRTCOMPBUFFER*

Address of a pointer to the output ID3DXPRTCompBuffer object.

Return value

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

Remarks

The compiler setting also determines the function version. If Unicode is defined, the function call resolves to D3DXLoadPRTCompBufferFromFileW. Otherwise, the function call resolves to D3DXLoadPRTCompBufferFromFileA.
