[Numpy-discussion] Owndata flag

[Fabrice Silva]

How can one arbitrarily assumes that an ndarray owns its data ?

More explicitly, I have some temporary home-made C structure that holds
a pointer to an array. I prepare (using Cython) an numpy.ndarray using
the PyArray_NewFromDescr function. I can delete my temporary C structure
without freeing the memory holding array, but I wish the numpy.ndarray
becomes the owner of the data. 

How can do I do such thing ?
