The mechanism or handshake

[strmnati]

I want to know that how OpenGL work with OS or said environment. Is there any handshake exist or related documents?
Another question is that. Is it possible let hardware have a concept of object not just vertices.

What do you mean by handshake ?
In general the implementation details of GL drivers are not public, unless driver is opensource.

I mean the detail mechanism of gpu and cpu communication. How API trigger GPU to draw, how CPU knows send information to GPU, kind of those things.
Thanks for your replying !
