Overview
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.
Diagnostics
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.
