# 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.
