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.

Opportunity

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.

Free Books

The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.

Education

Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
