storableCast :: (Storable a, Storable b) => a -> IO b Source #
storableCast works like storableCastArray, except that it
takes a single value and returns a single value.
storableCastArray :: (Storable a, Storable b) => [a] -> IO [b] Source #
storableCastArray takes a list of values of a first type, stores it
at a contiguous memory area (that is first blanked with 0s), and then
reads it as if it was a list of a second type, with enough elements to
fill at least the same space.
