libvorbis audio decode from memory in C++

Question

Given an encoded buffer in C++, what would be the steps using oggvorbis structs to decode the already in-memory data?

OggVorbis_File cannot be used, because assets are w

You also can don't reinvent the wheel and use fmemopen like this:

FILE* memfile = fmemopen(data, len, "r");

Where data is pointer to memory beginning and len is length of your data. Then pass memfile to ov_open like regular FILE object.

However, there is downside: this function seems linux-specific (but it can be found in arduino, so I'm a bit confused about its status), so you don't have it on other systems. But there is some implementations for them (check libconfuse for window or for apple OSes).
