Hello, For integrating some codes I try to use PyCObjects with Numeric interfaces. I have PyCObjects that contain several arrays. I want to provide these arrays to Python as Numeric arrays using PyArray_FromDimsAndData, the arrays could grow quite large, so I want to handle arround references, not copies. Of course this is dangerous. If I destroy the PyCObject and try to access the Numeric array referencing its data later, who knows what happens. It would be nice to have some callback function slot to allow to increase the refcount of the PyCObject when a Numeric array with a reference is created and to decrease it when the array is deleted. Is there a way to achive this. Further after skimming over the numarray documentation it seems PyArray_FromDimsAndData and similar functions for numarray are copiing the data instead of using a reference. Is this true? If yes, is it planned to provide a method for generating numarray arrays using references only?
