[SciPy-Dev] Multivariate ctypes integration PR

[Nathan Woods]

We had a question about how to implement one of the suggested improvements:

"- The code should more carefully check that the whole ctypes signature
  matches"

>From what we can tell (see e.g.
http://stackoverflow.com/questions/18775389/is-there-a-way-to-load-the-constant-values-stored-in-a-header-file-via-ctypes),
there is no way to automatically generate the ctypes function signature
directly from a .h header file or c function prototype. This means that any
ctypes library function must be assumed to have the function signature that
the user claims it does (by specifying argtypes & restype). Unfortunately,
the ctypes library load & specification commands are executed by the user,
not by the library, so there's no way to enforce the function signature.

Maybe there's a way in Cython or f2py, but we think that ctypes should
probably be supported anyway, even if it is with an "use at own risk"
disclaimer.
