#define VT_RELDISP _IO('v', 4 /*, int */)
Whether and How we will Release the display?
int == VT_FALSE, user refused to switch
== VT_TRUE, has released
== VT_ACKACQ, acquire ackownledged, switch completed
This ioctl() always called in release signal handler.
When the release signal occured, the handler call VT_RELDISP
to perform the action.
------------------------------------------------------------------------------
#define VT_ACTIVATE _IO('v', 5 /*, int */)
Switch to scrren specified by the parameter ( from 1 )
------------------------------------------------------------------------------
#define VT_WAITACTIVE _IO('v', 6 /*, int */)
VT_ACTIVATE just start the switch action, to wait for its completion,
VT_WAITACTIVATE must be called. When return, the switch is completed.
the param is the new console index
------------------------------------------------------------------------------
#define VT_GETACTIVE _IOR('v', 7, int)
#define VT_GETACTIVE _IOR('v', 7, int)
