I understand that SWIG, Boost, et. al are perhaps too heavyweight for
this one use, but you might want to give Cython a try. It makes it
really easy to grab a numpy array (and tst it for compliance), and then
you can do whatever you want with the data pointer:
http://wiki.cython.org/tutorials/numpy
http://wiki.cython.org/WrappingNumpy (this one is marked as depricated,
but may be what you want in your case, as you do want a raw C array)
Some wore googling and browsing of the Cython list will likely yield
examples similar to yours.
