The FFI for C has been around for a while now so I was unhappy to find out that calling pointers to C functions is not implemented yet. Because of this issue in the test case for the code here: http://gitorious.org/rust-dlfcn/rust-dlfcn/blobs/master/dlfcn.rs . I must use incorrect code, and use extern fn, instead of extern "C" fn for the type of the cosine function pointer. I understand that this is okay for C functions which do not use up that much stack space but in general one would want to use the extern "C" fn type.
