Hi,
I don't know if that was raised or not, but in np1.7b2 doing this fail with this error message:
PyArray_BYTES(obj)=ptr
file:lne_number:offset: error: lvalue required as left operatnd of assignment.
I tried with PyArray_DATA(obj)=ptr and this also fail.
Do you want to remove this feature now? I would think this change will be done at the same time as the one related to the macro NPY_NO_DEPRECATED_API.
If I missed the discussion about this, tell me.
f2py wants to do the same thing, i.e., change the data pointer of an existing array, which is why NPY_NO_DEPRECATED_API is not defined in that module. I had some discussion off list with Pearu about that but it petered out. I think for this sort of thing is a new function needs to be implemented. What precisely is your application? IIRC, Pearu was using it to exchange pointers between two arrays to avoid a copy. Chuck
