Detailed Description

C++ interface of the Vbus API.

The virtual bus (Vbus) is a hierarchical (tree) structure of device nodes where each device has a set of resources attached to it. Each virtual bus provides an Icu (Interrupt controller) for interrupt handling.

The Vbus interface allows a client to find and query devices present on his virtual bus. After obtaining a device handle for a specific device the client can enumerate its resources.

Refer to L4 Vbus functions for the C API.
