[cffi-devel] passing a list of numbers to double *

[Tamas K Papp]

Hi,

I have a function that looks like this:

void myfunction(const double *values, int num_values);

that expects a C array of doubles along with its length.  SWIG
generated the CFFI interface

(cffi:defcfun ("myfunction" myfunction) :void
  (values :pointer)
  (num_values :int))

Imagine that I have a list '(1d0 2d0 3d0).  What is the easiest way
to call this function with these values?

I am reading the CFFI documentation, but could not find this, sorry if
this is an obvious question, just please point me in the right
direction.

Thanks,

Tamas
