D3DXVec4Add Function

Adds two 4-D vectors.

Syntax

D3DXVECTOR4 *D3DXVec4Add(      

    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 Value

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

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec4Add function can be used as a parameter for another function.
