Hello,

I'm trying to use the fftw binding, and its functions operate on CArrays of Complex. My data is coming from hsndfile, so it starts out as a Vector of Double. How do I convert this data to CArray? The API functions in the CArray module don't seem to indicate how.

I think only way is to go though lists. CArray and vector package use different primitives.

listArray (0, V.length v) $ V.toList v
