-.SH DESCRIPTION
-The X Window System provides support for changing the image on a
-display screen after a user-settable period of inactivity to avoid
-burning the cathode ray tube phosphors.
-However, no interfaces are provided for the user to control the image
-that is drawn.
-This extension allows an external ``screen saver'' client to detect
-when the alternate image is to be displayed and to provide the
-graphics.
-.PP
-Current X server implementations typically provide at least one form of
-``screen saver'' image.
-Historically, this has been a copy of the X logo drawn against the
-root background pattern.
-However, many users have asked for the mechanism to allow them to
-write screen saver programs that provide capabilities similar to those
-provided by other window systems.
-In particular, such users often wish to be able to display corporate
-logos, instructions on how to reactivate the screen, and automatic
-screen-locking utilities.
-This extension provides a means for writing such clients.
-.SS Assumptions
-This extension exports the notion of a special screen saver window that is
-mapped above all other windows on a display.
-This window has the \fIoverride-redirect\fP attribute set so that it
-is not subject to manipulation by the window manager.
-Furthermore, the X identifier for the window is never returned by
-\fBQueryTree\fP requests on the root window, so it is typically not
-visible to other clients.
-.PP
-.B XScreenSaverQueryExtension
-returns
-.B True
-if the
-.I XScreenSaver
-extension is available on the given display.
-A client must call
-.B XScreenSaverQueryExtension
-before calling any other XScreenSaver function in order
-to negotiate a compatible protocol version; otherwise the client will
-get undefined behavior (XScreenSaver may or may not work).
-.PP
-If the extension is supported, the event number for
-.I ScreenSaverNotify
-events is returned in the value pointed to by \fIevent_base\fP.
-Since no additional errors are defined by this extension, the results
-of \fIerror_base\fP are not defined.
-.PP
-.B XScreenSaverQueryVersion
-returns
-.B True
-if the request succeeded; the values of the major and minor protocol
-versions supported by the server are returned in
-.I major_versionp
-and
-.I minor_versionp .
-.PP
-.B XScreenSaverAllocInfo
-allocates and returns an \fBXScreenSaverInfo\fP structure
-for use in calls to \fBXScreenSaverQueryInfo\fP.
-All fields in the structure are initialized to zero.
-If insufficient memory is available, NULL is returned.
-The results of this routine can be released using \fIXFree\fP.
-.PP
-.B XScreenSaverQueryInfo
-returns information about the current state of the
-screen server in \fIsaver_info\fP and a non-zero value is
-returned.
-If the extension is not supported, \fIsaver_info\fP is not changed and 0
-is returned.
-.br
-The \fIstate\fP field specifies whether or not the screen saver is currently
-active and how the \fItil-or-since\fP value should be interpreted:
-.TP 4
-.I Off
-The screen is not currently being saved; \fItil-or-since\fP
-specifies the number of milliseconds until the screen saver is expected to
-activate.
-.TP 4
-.I On
-The screen is currently being saved; \fItil-or-since\fP specifies
-the number of milliseconds since the screen saver activated.
-.TP 4
-.I Disabled
-The screen saver is currently disabled; \fItil-or-since\fP is zero.
-.br
-The \fIkind\fP field specifies the mechanism that either is currently being
-used or would have been were the screen being saved:
-.TP 4
-.I Blanked
-The video signal to the display monitor was disabled.
-.TP 4
-.I Internal
-A server-dependent, built-in screen saver image was displayed; either no
-client had set the screen saver window attributes or a different client
-had the server grabbed when the screen saver activated.
-.TP 4
-.I External
-The screen saver window was mapped with attributes set by a
-client using the \fBScreenSaverSetAttributes\fP request.
-.PP
-The \fIidle\fP field specifies the number of milliseconds since the last
-input was received from the user on any of the input devices.
-.br
-The \fIevent-mask\fP field specifies which, if any, screen saver
-events this client has requested using \fBScreenSaverSelectInput\fP.
-.PP
-.B XScreenSaverSelectInput
-asks that events related to
-the screen saver be generated for this client.
-If
-no bits are set in \fIevent-mask\fP, then no events will be generated.
-Otherwise, any combination of the following bits may be set:
-.TP 8
-.B ScreenSaverNotify
-If this bit is set, \fBScreenSaverNotify\fP events are generated whenever
-the screen saver is activated or deactivated.
-.TP 8
-.B ScreenSaverCycle
-If this bit is set, \fBScreenSaverNotify\fP events are generated whenever
-the screen saver cycle interval passes.
-.PP
-.B XScreenSaverSetAttributes
-sets the attributes to be used
-the next time the external screen saver is activated.
-If another client currently has the attributes set,
-a BadAccess error is generated and the request is ignored.
-.br
-Otherwise, the specified window attributes are checked as if
-they were used in a core \fBCreateWindow\fP request whose
-parent is the root.
-The \fIoverride-redirect\fP field is ignored as it is implicitly set
-to True.
-If the window attributes result in an error according to the rules for
-\fBCreateWindow\fP, the request is ignored.
-.br
-Otherwise, the attributes are stored and will take effect on the next
-activation that occurs when the server is not grabbed by another client.
-Any resources specified for the
-\fIbackground-pixmap\fP or \fIcursor\fP attributes may be
-freed immediately.
-The server is free to copy the \fIbackground-pixmap\fP or \fIcursor\fP
-resources or to use them in place; therefore, the effect of changing
-the contents of those resources is undefined.
-If the specified \fIcolormap\fP no longer exists when the screen saver
-activates, the parent's colormap is used instead.
-If no errors are generated by this request, any previous screen saver
-window attributes set by this client are released.
-.br
-When the screen saver next activates and the server is not grabbed by
-another client, the screen saver window is
-created, if necessary, and set to the specified attributes and events
-are generated as usual.
-The colormap associated with the screen saver window is installed.
-Finally, the screen saver window is mapped.
-.br
-The window remains mapped and at the top of the stacking order
-until the screen saver is deactivated in response to activity on
-any of the user input devices, a \fBForceScreenSaver\fP request with
-a value of Reset, or any request that would cause the window to be
-unmapped.
-.br
-If the screen saver activates while the server is grabbed by another
-client, the internal saver mechanism is used.
-The \fBForceScreenSaver\fP request may be used with a value of Active
-to deactivate the internal saver and activate the external saver.
-.br
-If the screen saver client's connection to the server is broken
-while the screen saver is activated and the client's close down mode has not
-been RetainPermanent or RetainTemporary, the current screen saver
-is deactivated and the internal screen saver is immediately activated.
-.br
-When the screen saver deactivates, the screen saver window's colormap
-is uninstalled and the window is unmapped (except as described below).
-The screen saver XID is disassociated
-with the window and the server may, but is not required to,
-destroy the window along with any children.
-.br
-When the screen saver is being deactivated and then immediately
-reactivated (such as when switching screen savers), the server
-may leave the screen saver window mapped (typically to avoid
-generating exposures).
-.PP
-.B XScreenSaverUnsetAttributes
-instructs the server to discard
-any previous screen saver window attributes set by this client.
-.PP
-.B XScreenSaverRegister
-stores the given \fIXID\fP in the \fB_SCREEN_SAVER_ID\fP
-property (of the given \fItype\fP) on the
-root window of the specified \fIscreen\fP.
-It returns zero if an error is encountered and the property is not
-changed, otherwise it returns non-zero.
-.PP
-.B XScreenSaverUnregister
-removes any \fB_SCREEN_SAVER_ID\fP from the
-root window of the specified \fIscreen\fP.
-It returns zero if an error is encountered and the property is
-changed, otherwise it returns non-zero.
-.PP
-.B XScreenSaverGetRegistered
-returns the \fIXID\fP and \fItype\fP stored in
-the \fB_SCREEN_SAVER_ID\fP property on the
-root window of the specified \fIscreen\fP.
-It returns zero if an error is encountered or if the property does not
-exist or is not of the correct format; otherwise it returns non-zero.
-.SH "ERRORS"
