Function sioul_wake_next 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn sioul_wake_next(
    zone: *const c_char,
    fetch: bool,
) -> *mut c_char

next, for Java (android/main.cpp); a panic is answered as not known, so that Java keeps the wakings it has. Given back to sioul_string_free.

Safety

zone is null, or a zero-terminated text valid for the call.
