32
33       barriers
34              List of deviceid, barrier, eventid triplets.

DESCRIPTION

40           If a pointer is constrained by a pointer barrier, release the pointer
41           from the barrier and allow it to cross the barrier with the next motion.
42           If the pointer moves away from the barrier, this request does nothing.
43
44           This request only releases the pointer for the given barrier event
45           sequence. If the pointer moves away from or through the barrier, a
46           XI_BarrierLeave event is generated. Future pointer movement constrained
47           by this barrier will assign a new eventid and require a new
48           XIBarrierReleasePointer request.
49
50           If the pointer is not currently blocked by the barrier or the barrier
51           event sequence has ended, this request does nothing.
52
53           XIBarrierReleasePointer and XIBarrierReleasePointers can generate a
54           BadDevice or BadValue error.
55

DIAGNOSTICS

57           BadDevice
58                  An invalid device was specified. The device does not
59                  exist or is not a master pointer device.
60
61           BadValue
62                  A value for a PointerBarrier argument does not name a defined
63                  pointer barrier.
