/// @class HostInfo HostInfo.h "lldb/Host/HostProcess.h"
/// @brief A class that represents a running process on the host machine.
///
/// HostProcess allows querying and manipulation of processes running on the
/// host machine.  It is not intended to be represent a process which is
/// being debugged, although the native debug engine of a platform may likely
/// back inferior processes by a HostProcess.
///
/// HostProcess is implemented using static polymorphism so that on any given
/// platform, an instance of HostProcess will always be able to bind statically
/// to the concrete Process implementation for that platform.  See HostInfo
/// for more details.
