We are calling bs3_curve_to_array to retrieve the definition data for the
curve.  Afterwards, we are deleting the arrays of control points, knots,
etc. using

delete [] knots;
delete [] ctrlPts;
etc.

Now, we are trying to check our code and the checker is reporting that we
are trying to delete memory that was malloc'ed, rather than created with
new.  I have used these calls in previous versions of ACIS and delete [] was
the right way to go.  Has something changed?  Am I now supposed to use free?
We are running on ACIS R8.x.

Thank you for any help you can provide.

Alan

HI,
 
Suppose I ve a two entities A & B.if I save the pointer of  A as an
attribute in B and B's  pointer in a A .when I try to delete A then
obviously  B will delete .
My question is is there any way to restrict B from deleting. I ve used
entity_notification_handler to track delete_entity but it wouldn't work.
 
Thanks in advance
 
Gulshan
