HBLAS.BLAS.FFI types

[mxswd]

The types of the functions (i.e. cblas_sdot_unsafe) are Float and Double, when they are really CFloat and CDouble.

Also cblas_isamax_unsafe / cblas_idamax_unsafe is returning a CInt, when really it returns a CUInt.

Also, cblas_idamax_unsafe's 2nd argument takes a Float, when it should take a Double?

is there any difference between CFloat vs Float and CDouble vs Double for the purposes of FFI? AFAIK, the C* versions of float and double are just newtype wrappers and then the ghc ffi work treats them as Float and Double? (i could be totally wrong here, so please correct me if i'm wrong.)

Good catch #define CBLAS_INDEX size_t seems to the the right defn, so it should be CSize right?

you're right, i'll check that shortly.

Yeah, leave the Floats and Doubles.
