[C++] Unable to insert uprobe at arbitrary file offset?

My purpose is to dynamically instrument a stripped binary with an ability to insert uprobes at arbitrary file offsets (that are aligned to instructions of course, not completely arbitrary).

I've tried to use ```attach_uprobe``` method from C++ API, but it seems to work only when a binary has symbols, whereas Python API seems to support arbitrary offset probing and thus works well with stripped binaries. Do I try to use a wrong method for that purpose or C++ API simply doesn't support it? Thank you in advance.
