15 /// A class that represents a running process on the host machine.
16 ///
17 /// HostProcess allows querying and manipulation of processes running on the
18 /// host machine.  It is not intended to be represent a process which is being
19 /// debugged, although the native debug engine of a platform may likely back
20 /// inferior processes by a HostProcess.
21 ///
22 /// HostProcess is implemented using static polymorphism so that on any given
23 /// platform, an instance of HostProcess will always be able to bind
24 /// statically to the concrete Process implementation for that platform.  See
25 /// HostInfo for more details.
