NAME
       XIBarrierReleasePointer, XIBarrierReleasePointers - allow pointer
       movement across a pointer barrier

SYNOPSIS
       #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.

DESCRIPTION
           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.
