# NAME

XIWarpPointer - move a device's pointer.

# SYNOPSIS

    #include <X11/extensions/XInput2.h>

    Bool XIWarpPointer( Display *display,

                        int deviceid,

                        Window src_w,

                        Window dest_w,

                        double src_x,

                        double src_y,

                        int src_width,

                        int src_height,

                        double dest_x,

                        double dest_y);

    dest_w

           Specifies the destination window or None.

    dest_x, dest_y

           Specify the x and y coordinates within the destination

           window.

    deviceid

           Specifies the master pointer device or floating slave

           device to move.

    display

           Specifies the connection to the X server.

    src_x, src_y, src_width, src_height

           Specify a rectangle in the source window.

    src_w

           Specifies the source window or None.

# DESCRIPTION

    If dest_w is None, XIWarpPointer moves the pointer by the
    offsets (dest_x, dest_y) relative to the current position of
    the pointer. If dest_w is a window, XIWarpPointer moves the
    pointer to the offsets (dest_x, dest_y) relative to the origin
    of dest_w. However, if src_w is a window, the move only takes
    place if the window src_w contains the pointer and if the
    specified rectangle of src_w contains the pointer.

    The src_x and src_y coordinates are relative to the origin of
    src_w. If src_height is zero, it is replaced with the current
    height of src_w minus src_y. If src_width is zero, it is
    replaced with the current width of src_w minus src_x.

    There is seldom any reason for calling this function. The
    pointer should normally be left to the user. If you do use this
    function, however, it generates events just as if the user had
    instantaneously moved the pointer from one position to another.
    Note that you cannot use XIWarpPointer to move the pointer
    outside the confine_to window of an active pointer grab. An
    attempt to do so will only move the pointer as far as the
    closest edge of the confine_to window.

    XIWarpPointer is identical to XWarpPointer but specifies the
    device explicitly.

    XIWarpPointer can generate a BadDevice and a BadWindow error.

# DIAGNOSTICS

    BadDevice

           An invalid device was specified. The device does not

           exist or is not a pointer device.

    BadWindow

           A value for a Window argument does not name a defined

           window.
