Function register_vec 

pub fn register_vec<T: Copy>(
    vec: &mut Vec<T>,
    flags: RegisterFlags,
) -> CudaResult<RegisteredMemory<T>>

Convenience: registers a Vec<T> with the CUDA driver.

The Vec must not be reallocated (e.g. via push, resize) while the returned handle is alive, as that would invalidate the registered pointer.

Errors

Same as register.
