int get_vector_angle_in_degrees
(
	const Vector *vp1,
	const Vector *vp2,
	double *result_ptr
);

DESCRIPTION

This routine computes the angle between two vectors in degrees and puts the result in *result_ptr.

RETURNS

NO_ERROR on success, and ERROR on failure. This routine will fail if either of the vectors is too close to zero, or the vectors are of un-equal length. It should be noted that this error is currently treated as bug (see kjb_bug(3)).

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
