+
+.B XRRScreenConfiguration
+This is an opaque data type containing the configuration information

+
+.B Timestamps
+.PP
+Time stamps are included and must be used to ensure the client is playing

+on the fly and this ensures its knowledge of the configuration is up to date.
+This is to help issues when screens may become hot-pluggable in the future.
+
+.SH DESCRIPTION
+.B Xrandr
+is a simple library designed to interface the X Resize and Rotate
+Extension.  This allows clients to change the size and rotation of the
+root window of a screen, along with the ability to reflect the screen
+about either axis (if supported by the implementation).  Rotation and
+reflection may be implemented by software and may result in slower
+performance if rotation and reflection are implemented in this fashion 
+(as are all implementations as of October 2002).
+.PP
+The Xrandr library does some minimal caching to avoid roundtrips to
+provide clients frequently used information.  See "The X Resize and
+Rotate Extension" for a detailed description; also note that depth
+switching, as described in the document is not implemented, and may
+(or may not) ever be implemented, as display memory is growing rapidly,
+and toolkits are already beginning to support migration, mitigating the
+need for depth switching.  If it is implemented in the future, we
+expect to do so via an upward compatible extension to the
+current library/protocol; functionality described here should continue
+to work.
+.PP
+Rotation and reflection and how they interact can be confusing.  In
+Randr, the coordinate system is rotated in a counter-clockwise
+direction relative to the normal orientation.  Reflection is along the
+window system coordinate system, not the physical screen X and Y axis,
+so that rotation and reflection do not interact.  The other way to
+consider reflection is to is specified in the "normal" orientation,
+before rotation, if you find the other way confusing.
+.PP
+The 
+.B XRRScreenChangeNotify 
+event is sent to clients that ask to be informed whenever the root window
+configuration changes.  Configuration changes may include resolution,
+physical size, subpixel order (see XRender(3)), and rotation.  Note
+that changes to any or all of these could occur due to external events
+(user control in the X server, a different monitor/flat panel display
+being hot-plugged) and is not only the result of a protocol/library
+request to the X server.
+.PP
+Additionally, to eliminate a potential race condition, 
+this event may be generated
+immediately upon selecting for notification if the screen has changed
+since the client of Xrandr connected to the X server, to enable
+reliable screen resolution changing when a user may log in and
+change the configuration while one or many clients are starting up.
+.PP
+.B Xlib notification
+.PP
+Clients must call back into Xlib using
+.B XRRUpdateConfiguration
+when screen configuration change notify events are generated
+(or root window configuration changes occur, to update Xlib's
+view of the resolution, size, rotation, reflection or subpixel order.
+Generally, toolkits will perform this operation on behalf of applications;
+we did not want to change display structure data behind the back of toolkits,
+as in multithreaded clients, various race conditions might occur.
+Toolkits should provide clients some mechanism for notification of
+screen change, of course.
+
+.SH FUNCTIONS
+There are two classes of interfaces: those which can be safely called
+even if RandR is not implemented on a screen (to make common idioms not
+dependent on the server having support), and those which will return
+errors if the extension is not present.
+.PP
+.B XRRRotations
+returns both the possible set of rotations/reflections supported
+(as a bitmask) as the value of the function, along with the current
+rotation/reflection of the screen.
+.PP
+.B XRRSizes
+returns the size and a pointer to the current sizes supported by
+the specified screen.  The first size specified is the default size
+of the server. If RandR is not supported, it returns 0 for
+the number of sizes.
+.PP
+.B XRRRates
+returns a pointer to a the rates supported by the specified size.
+If RandR is not supported, it returns 0 for the number of rates.
+.PP
+.B XRRTimes
+returns the time last reported by the server along with the
+timestamp the last configuration changed.
+If the configuration has changed since the client last updated
+its view of the server time, requests to change the configuration
+will fail until the client has an up to date timestamp.
+.PP
+.B XRRRootToScreen
+returns the screen number given a root window (for example, from
+an \fBXRRScreenChangeNotifyEvent\fI.
+.PP
+The rest of the functions will fail if applied to screens not
+implementing the RandR extension.
+.B XRRSetScreenConfig
+sets the screen size and rotation and reflection to the desired
+values on the screen specified by \fIdraw\fP, or returns a
+.B BadValue
+error.
+\fIsize_index\fP specifies which size configuration is to be used,
+\fIrotation\fP specifies which rotation or reflection is to
+be used (or a 
+.B BadValue
+error is returned).
+The \fItimestamp\fP is used by the server to make sure the client
+has up to date configuration information. Status is returned
+to indicate success or failure; a client must refresh its configuration
+information if it fails and try the call again (by calling 
+\fBXRRGetScreenInfo\fP).
+.PP
+.B XRRSetScreenConfigAndRate
+like
+.B XRRSetScreenConfig
+but also set the refresh rate. If specified rate is not supported a
+.B BadValue
+error is returned.
+.PP
+.B XRRConfigRotations,
+.B XRRConfigSizes,
+.B XRRConfigCurrentConfiguration,
+.B XRRConfigTimes,
+.B XRRConfigRates,
+and
+.B XRRConfigCurrentRate
+are used to get specific configuration information out of a screen
+configuration.
+.PP
+.B XRRGetScreenInfo
+Returns a screen configuration for later use; the information is
+private to the library.
+Call
+.B XRRFreeScreenConfigInfo
+to free this information when you are finished with it.
+It forces a round trip to the server.
+
+Other functions include:
+.B XRRQueryExtension
+which returns the event and error base codes,
+.B XRRQueryVersion
+, which returns the current version of the extension (this information
+is cached by the library).
+.SH RESTRICTIONS
+.B Xrandr
+will remain upward compatible after the current 1.0 release.
