D3DXVec4Scale function

Scales a 4D vector.

Syntax


D3DXVECTOR4* D3DXVec4Scale(
  _Inout_       D3DXVECTOR4 *pOut,
  _In_    const D3DXVECTOR4 *pV,
  _In_          FLOAT       s
);

Parameters

pOut [in, out]

Type: D3DXVECTOR4*

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

pV [in]

Type: const D3DXVECTOR4*

Pointer to the source D3DXVECTOR4 structure.

s [in]

Type: FLOAT

Scaling value.

Return value

Type: D3DXVECTOR4*

Pointer to the D3DXVECTOR4 structure that is the scaled vector.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec4Scale function can be used as a parameter for another function.
