Function siglus_game_name_from_dir 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn siglus_game_name_from_dir(
    game_root_utf8: *const c_char,
) -> *mut c_char

Return the game name, or the default name if the path is null or unavailable. Free a non-null result with siglus_string_free.

Safety

If non-null, game_root_utf8 must point to a NUL-terminated string in a single readable allocation of at most isize::MAX bytes, including the terminator. The bytes must remain valid and unchanged for this call.
