Struct vt::Console

pub struct Console { /* fields omitted */ }

Handle to a console device file, usually located at /dev/console. This structure allows managing virtual terminals.

Methods

impl Console

pub fn open() -> Result<Console, Error>

Opens a new handle to the console device file.

pub fn current_vt(&self) -> Result<Vt>

Returns the currently active virtual terminal.

pub fn new_vt(&self) -> Result<Vt>

Allocates a new virtual terminal. To switch to the newly created terminal, use Vt::switch or Console::switch_to.

pub fn new_vt_with_minimum_number(&self, min: u16) -> Result<Vt>

Allocates a new virtual terminal with a number greater than or equal to the given number. Be careful not to exaggerate too much with the minimum threshold: usually systems have a maximum number of 16 or 64 vts.

To switch to the newly created terminal, use Vt::switch or Console::switch_to.

pub fn switch_to(&self, vt_number: u16) -> Result<()>

Switches to the virtual terminal with the given number.

pub fn lock_switch(&self, lock: bool) -> Result<()>

Enables or disables virtual terminal switching (usually done with Ctrl + Alt + F<n>).

pub fn blank_timer(&self) -> Result<u32>

Returns the current console blank timer value. A value of 0 means that the timer is disabled. To change the blank timer, use the Vt::set_blank_timer method.
