D3DXVec4Subtract

Subtracts two 4-D vectors.

D3DXVECTOR4* D3DXVec4Subtract(
  D3DXVECTOR4* pOut,
  CONST D3DXVECTOR4* pV1,
  CONST D3DXVECTOR4* pV2
); 

Parameters

pOut

[in, out] Pointer to the D3DXVECTOR4 structure that is the result of the operation.

pV1

[in] Pointer to a source D3DXVECTOR4 structure.

pV2

[in] Pointer to a source D3DXVECTOR4 structure.

Return Values

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.

Requirements

  Header: Declared in D3dx8math.h.
  Import Library: Use D3dx8.lib.
