XIBARRIERRELEASEPOIN(3) 												   XIBARRIERRELEASEPOIN(3)

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.
