D3DXVec2Subtract

The D3DXVec2Subtract function subtracts two 2-D vectors.

D3DXVECTOR2* D3DXVec2Subtract(
  D3DXVECTOR2* pOut,
  const D3DXVECTOR2* pV1,
  const D3DXVECTOR2* pV2
); 

Parameters

pOut

A pointer to the D3DXVECTOR2 structure that is the result of the operation.

pV1

A pointer to a source D3DXVECTOR2 structure.

pV2

A pointer to a source D3DXVECTOR2 structure.

Return Values

A pointer to a D3DXVECTOR2 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 D3DXVec2Subtract function can be used as a parameter for another function.
