Hello, Forgive me if this is a stupid question, I've been looking around all the Cython documentation and I can't find out if this is possible.
What I would like to do is generally is wrap a C function that takes a double array, and be able to pass in a numpy array, I was wondering if it's possible to do this using the buffer interface? I understand I could do it using this method (http://wiki.cython.org/WrappingNumpy), but the buffer interface seems much neater. Specifically, I have a C function that I would like to wrap with signature: #### cfile.h double do_something(double * array, int len); I was hoping with the buffer interface, I could do something like this: #### pyfile.pyx import numpy cimport numpy cdef extern from "cfile.h" double do_something(double * array, int len) cdef do_something_python(numpy.ndarray[numpy.float64, ndim = 1] numarr): cdef double x cdef double * data cdef int l data = ... # Not sure what to do here l = numarr.shape[0] x = do_something(data, l) The above probably doesn't work for many reasons (I've just jotted it down), but the think I can't figure out is what to do at the "data = ..." line. Any help would be greatly appreciated!
