See tools/virsh-console.c for an example use of virDomainOpenConsole.
virDomainOpenGraphics is probably similar.
2.what is the theory of that?
Your question is very vague. What are you trying to accomplish, so that
we can better determine how to answer it?

the theory , i mean how libvirt get guest's console( or graphic
screen), via what kind of channel, then how libvirt show guest's screen.
Libvirt has a notion of a virStreamPtr, which is an object which tracks
an arbitrary pass-through channel. Any API such as virDomainOpenConsole
that needs to pass data in both directions between the client and the
source opens up a virStreamPtr, then passes that data alongside all the
other RPC calls. For more details on how the data is passed, read
docs/internals/rpc.html, and look at the stream type packets. A
virStreamPtr is also used under the hood in tunneled migration.
