void clear_selection

(

void

)

clear_selection - remove current selection

Remove the current selection highlight, if any from the console holding the selection. The caller must hold the console lock.

int sel_loadlut

(

char __user *

p

)

set loadlut - load the LUT table : user table

Load the LUT table from user space. The caller must hold the console lock. Make a temporary copy so a partial update doesn't make a mess.

Definition at line 106 of file selection.c.

int set_selection	(	const struct tiocl_selection __user *	sel,
		struct tty_struct *	tty
	)

set_selection - set the current selection. : user selection info : the console tty

Invoked by the ioctl handle for the vt layer.

The entire selection process is managed under the console_lock. It's a lot under the lock but its hardly a performance path
