Q3Vector2D_Negate
You can use the Q3Vector2D_Negate function to negate a two-dimensional vector.
TQ3Vector2D *Q3Vector2D_Negate (
const TQ3Vector2D *vector2D, 
TQ3Vector2D *result);
vector2D
A two-dimensional vector.
result
On exit, the negation of the specified vector.

DESCRIPTION
The Q3Vector2D_Negate function returns, as its function result and in the result parameter, the vector that is the negation of the vector vector2D.
