Long can be 32-bit or 64-bit, depending on the platform. The types available in Numpy are listed here, including the information which of them are compatible with which C types: http://docs.scipy.org/doc/numpy/reference/arrays.scalars.html The C long seems not to be listed -- but it's the same as "Python int", i.e., np.int_ will work. IIRC, the Numpy type codes, dtype.kind, map directly to C types.
