The is-connected command returns success if the given plug or slot of the
calling snap is connected, and failure otherwise.

$ snapctl is-connected plug
$ echo $?
1

Snaps can only query their own plugs and slots - snap name is implicit and
implied by the snapctl execution context.

The --list option lists all connected plugs and slots.

The --pid and --aparmor-label options can be used to determine whether
a plug or slot is connected to the snap identified by the given
process ID or AppArmor label. In this mode, additional failure exit
codes may be returned: 10 if the other snap is not connected but uses
classic confinement, or 11 if the other process is not snap confined.

The --pid and --apparmor-label options may only be used with slots of
interface type "pulseaudio", "audio-record", or "cups-control".
