Functions
PedConstraint *	ped_constraint_any (const PedDevice *dev)
	Return a constraint that any region on the given device will satisfy.
void	ped_constraint_destroy (PedConstraint *constraint)
	Release the memory allocated for a PedConstraint constructed with ped_constraint_new().
void	ped_constraint_done (PedConstraint *constraint)
	Release the memory allocated for a PedConstraint constructed with ped_constraint_init().
PedConstraint *	ped_constraint_duplicate (const PedConstraint *constraint)
	Duplicate a constraint.
PedConstraint *	ped_constraint_exact (const PedGeometry *geom)
	Return a constraint that only the given region will satisfy.
int	ped_constraint_init (PedConstraint *constraint, const PedAlignment *start_align, const PedAlignment *end_align, const PedGeometry *start_range, const PedGeometry *end_range, PedSector min_size, PedSector max_size)
	Initializes a pre-allocated piece of memory to contain a constraint with the supplied default values.
PedConstraint *	ped_constraint_intersect (const PedConstraint *a, const PedConstraint *b)
	Return a constraint that requires a region to satisfy both a and b.
int	ped_constraint_is_solution (const PedConstraint *constraint, const PedGeometry *geom)
	Check whether geom satisfies the given constraint.
PedConstraint *	ped_constraint_new (const PedAlignment *start_align, const PedAlignment *end_align, const PedGeometry *start_range, const PedGeometry *end_range, PedSector min_size, PedSector max_size)
	Convenience wrapper for ped_constraint_init().
PedConstraint *	ped_constraint_new_from_max (const PedGeometry *max)
	Return a constraint that requires a region to be entirely contained inside max.
PedConstraint *	ped_constraint_new_from_min (const PedGeometry *min)
	Return a constraint that requires a region to entirely contain min.
PedConstraint *	ped_constraint_new_from_min_max (const PedGeometry *min, const PedGeometry *max)
	Return a constraint that requires a region to be entirely contained inside max, and to entirely contain min.
PedGeometry *	ped_constraint_solve_max (const PedConstraint *constraint)
	Find the largest region that satisfies a constraint.
PedGeometry *	ped_constraint_solve_nearest (const PedConstraint *constraint, const PedGeometry *geom)
	Return the nearest region to geom that satisfy a constraint.
