D3DXVec4Subtract function

Note

The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.

Subtracts two 4D vectors.

Syntax

D3DXVECTOR4* D3DXVec4Subtract(
  _Inout_       D3DXVECTOR4 *pOut,
  _In_    const D3DXVECTOR4 *pV1,
  _In_    const D3DXVECTOR4 *pV2
);

Parameters

pOut [in, out]

Type: D3DXVECTOR4*

Pointer to the D3DXVECTOR4 structure that is the result of the operation.

pV1 [in]

Type: const D3DXVECTOR4*

Pointer to a source D3DXVECTOR4 structure.

pV2 [in]

Type: const D3DXVECTOR4*

Pointer to a source D3DXVECTOR4 structure.

Return value

Type: D3DXVECTOR4*

Pointer to a D3DXVECTOR4 structure that is the difference of two vectors.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec4Subtract function can be used as a parameter for another function.
