The view, B, has a reference to A (stored in the base attribute) and has OWNDATA set to false so that its deallocator simply decreases the reference count on the array, A, that actually owns the data.
In the code look at the `array_dealloc` function in arrayobject.c and the base and OWNDATA flag-bit in the array-structure for details. -Travis _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
