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

Look at with-foreign-object. I have been doing other things so am not up to speed on newtypes, but there should be something there as powerful as specializing expand-to-foreign-dyn, if you need to pass double*s often.
Don't trust the binding generator: see chapter 4, "Wrapper generators".
