D3DXCOLOR * D3DXColorAdd( D3DXCOLOR * pOut, CONST D3DXCOLOR * pC1, CONST D3DXCOLOR * pC2 );
This function returns a pointer to a D3DXCOLOR structure that is the sum of two color values.
The return value for this function is the same value returned in pOut. In this way, the D3DXColorAdd function can be used as a parameter for another function.
