CGAL::compare_xyz() (2D/3D Linear Kernel)

Functions
template<typename Kernel >
Comparison_result	CGAL::compare_xyz (const CGAL::Point_3< Kernel > &p, const CGAL::Point_3< Kernel > &q)
	Compares the Cartesian coordinates of points p and q lexicographically in $xyz$ order: first $x$-coordinates are compared, if they are equal, $y$-coordinates are compared, and if both $x$- and $y$- coordinate are equal, $z$-coordinates are compared.
