In Stanix, a virtual console is an object attached to a framebuffer and a keyboard, virtual consoles can also be attached to a virtual terminal.

Virtual terminals (/dev/vtXX) and virtual consoles can be created from the virtual console master (/dev/vt).

ioctls

[!NOTE]
When doing a ioctl on a virtual terminal instead of the virtual console master, a lot of the time the operation can only be done on the virtual terminal used for this ioctl or it’s attached virtual console and a id of 0 will refere to the virtual terminal’s id or it’s atached virtual console one (a id of 0 in a ioctl passed to a virtual console master is not valid).
