Dear list members,<br>I have the following problem: I have wrapped a C library using the FFI and c2hs.<br>The C functions all take a bunch of pointers to C arrays of floats, doubles, or ints as arguments.<br>Naturally, the Haskell representation of these is e.g.<br>
 Ptr CFloat<br>or, for single values, CFloat.<br>My question is: if I have an array, e.g. allocated with mallocArray, to Haskell Float values (Ptr Float),<br>is the representation of Float exactly the same as for CFloat? Can I safely use Ptr Float where the C function<br>
expects the C type float* ?<br>I assume that I can not, and in that case I would like to find a way to have Float on the Haskell side and CFloat on the C side.<br>Any hint on how I would do that without copying data and without too large performance penalties?<br>
<br>Thanks a lot,<br>Christian<br>
