The method HostQuery() tries to establish a connection to the dbus and executes a method of host module on the host. 
My system is containerized. Various conatiners use HostQuery() to invoke a method on the host module, which is key_ctl.
key_ctl expects an array of strings.
host_client instantiates a proxy object to connect to the dbus interface.

With host_client.key_ctl(), code tries to execute the host module method. 


~~  Thanks, Srinadh

So what is that code doing, exactly?

(Sorry, I’m not familiar with C++ or whatever C++ libraries you might
be using.)
