Usage of SplineHelp.InitSplineWith() regarding flags -> returned data

[mogh]

Dear community,

Returned Data of Flag c4d.SPLINEHELPFLAGS_CONTINUECURVE unclear.

I've read that the SplineHelp() has flag called c4d.SPLINEHELPFLAGS_CONTINUECURVE.
While the written explanation is clear to me :
Continue the curvature of an existing spline at the end points.

Its unclear to me how to utilize the data or even how the data I get is different from a "normal" helper.

Reason of interest: I am coding a "Curvature" displaying Tag Plugin atm.

thank you for your time.
cheers mogh
