.SH "NAME"
XIBarrierReleasePointer, XIBarrierReleasePointers \- allow pointer movement across a pointer barrier
.SH "SYNOPSIS"
.sp
.nf
#include <X11/extensions/XInput2\&.h>
.fi
.sp
.nf
int XIBarrierReleasePointer( Display *display,
                             int deviceid,
                             PointerBarrier barrier,
                             BarrierEventID eventid);
.fi

int XIBarrierReleasePointers( Display *display,
                              XIBarrierReleasePointerInfo *barriers,
                              int num_barriers);
.fi
.sp
.nf
display
       Specifies the connection to the X server\&.
.fi
.sp
.nf
deviceid
       Specifies the device allowed to move across the barrier\&.
.fi
.sp
.nf
barrier
       Specifies the barrier\&.
.fi
.sp
.nf
eventid
       Specifies the unique event ID for this barrier event sequence\&.
.fi
.sp
.nf
barriers
       List of deviceid, barrier, eventid triplets\&.
.fi
.sp
.nf
num_barriers
       Number of elements in barriers\&.
.fi
.SH "DESCRIPTION"
.sp
.if n \{\
.RS 4
.\}
.nf
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\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
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\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
If the pointer is not currently blocked by the barrier or the barrier
event sequence has ended, this request does nothing\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
XIBarrierReleasePointer and XIBarrierReleasePointers can generate a
BadDevice or BadValue error\&.
.fi
.if n \{\
.RE
.\}
.SH "DIAGNOSTICS"
.sp
.if n \{\
.RS 4
.\}
.nf
BadDevice
       An invalid device was specified\&. The device does not
       exist or is not a master pointer device\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
BadValue
       A value for a PointerBarrier argument does not name a defined
       pointer barrier\&.
