XIBarrierReleasePointer, XIBarrierReleasePointers − allow pointer movement across a pointer barrier
#include <X11/extensions/XInput2.h>
int
XIBarrierReleasePointer( Display *display,
int deviceid,
PointerBarrier barrier,
BarrierEventID eventid);
int
XIBarrierReleasePointers( Display *display,
XIBarrierReleasePointerInfo *barriers,
int num_barriers);
display
Specifies the connection to the X server.
deviceid
Specifies the device allowed to move across the barrier.
barrier
Specifies the barrier.
eventid
Specifies the unique event ID for this barrier event
sequence.
barriers
List of deviceid, barrier, eventid triplets.
num_barriers
Number of elements in barriers.
If a pointer is
constrained by a pointer barrier, release the pointer
from the barrier and allow it to cross the barrier with the
next motion.
If the pointer moves away from the barrier, this request
does nothing.
This request
only releases the pointer for the given barrier event
sequence. If the pointer moves away from or through the
barrier, a
XI_BarrierLeave event is generated. Future pointer movement
constrained
by this barrier will assign a new eventid and require a new
XIBarrierReleasePointer request.
If the pointer
is not currently blocked by the barrier or the barrier
event sequence has ended, this request does nothing.
XIBarrierReleasePointer
and XIBarrierReleasePointers can generate a
BadDevice or BadValue error.
BadDevice
An invalid device was specified. The device does not
exist or is not a master pointer device.
BadValue
A value for a PointerBarrier argument does not name a
defined
pointer barrier.
