Function asdf_ndarray_block 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn asdf_ndarray_block(
    ndarray: *mut asdf_ndarray_t,
) -> *mut AsdfBlock

The block underlying an array, or null when its data is inline.

The view is opened on first use and owned by the array, so it must not be closed by the caller; it is released with the array.

Safety

ndarray must be null or a valid asdf_ndarray_t.
