Detailed Description

Callback interface from PCI devices to the host.

Devices get an instance of this object when they register themselves with the host using the PciHost::registerDevice() call.

Definition at line 91 of file host.hh.

Constructor & Destructor Documentation

DeviceInterface() [1/2]
