what is the afc:// URL, how to access it from my program?

I am using Linux (Mint)

I found that my phone files are visible in the file manager under "Devices" and I can browse the folders. But they seem to bee outside of file system (this is what bothers me).

Instead of a path name there is a URL name in the address bar:

afc://fc60223d846febfe2e059c2e7f4ff65b51ee0928:3/

How can I access that from my program? (Either C/C++ or Node.js)

I tried to search, but any combination of "linux", "afc", "url", "phone" does no good.

Update: here is my mount output:

AFC, to the best of my knowledge, stands for Apple File Connection.

To answer your question, your iDevice must've been attached to the GVFS virtual filesystem. To quote Wikipedia...

Attached resources are exposed via a URI syntax.

That's what afc://fc60223d846febfe2e059c2e7f4ff65b51ee0928:3/ is.
Futhermore, the Wikipedia article also says...

but are also mounted in the traditional manner under ~/.gvfs/

So you should probably take a look there as well. A Google search for "afc:" uri came up with this informative forum post which seems to be a duplicate of this very question.
