from `ioctl_tty(2)`:
|
|
|
|
Redirecting console output
|
|
TIOCCONS
|
|
Argument: void
|
|
|
|
Redirect output that would have gone to /dev/console or
|
|
/dev/tty0 to the given terminal. If that was a
|
|
pseudoterminal master, send it to the slave. In Linux
|
|
before version 2.6.10, anybody can do this as long as the
|
|
output was not redirected yet; since version 2.6.10, only
|
|
a process with the CAP_SYS_ADMIN capability may do this.
|
|
If output was redirected already, then EBUSY is returned,
|
|
but redirection can be stopped by using this ioctl with fd
|
|
pointing at /dev/console or /dev/tty0.
