);

Parameters

pDevice

[in] Pointer to an IDirect3DDevice9 interface, representing the device to be associated with the volume texture.

pWidth

[in, out] Pointer to the requested width in pixels, or NULL. Returns the corrected size.

pHeight

[in, out] Pointer to the requested height in pixels, or NULL. Returns the corrected size.

pDepth

[in, out] Pointer to the requested depth in pixels, or NULL. Returns the corrected size.

pNumMipLevels

[in, out] Pointer to the number of requested mipmap levels, or NULL. Returns the corrected number of mipmap levels.

Usage

[in] Currently not used, set to 0.

pFormat

[in, out] Pointer to a member of the D3DFORMAT enumerated type. Specifies the desired pixel format, or NULL. Returns the corrected format.

Pool

[in] Member of the D3DPOOL enumerated type, describing the memory class into which the volume texture should be placed.

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 values.

D3DERR_NOTAVAILABLE	This device does not support the queried technique.
