Function greentic_pack_export__prepare_flow 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn greentic_pack_export__prepare_flow(
    flow_id_ptr: *const u8,
    flow_id_len: usize,
    json_buffer: *mut u8,
    len: usize,
) -> usize

Safety

The caller must ensure that flow_id_ptr points to flow_id_len bytes of valid UTF-8 and that json_buffer points to a writable region of at least len bytes when non-null.
