-1. Overview

-

-    The client-to-server DMX extension to the X protocol (DMX) provides

-    normal client applications with the ability to determine information

-    about the characteristics of the Xdmx server and the back-end X

-    servers that DMX is using.

-

-    The name for this extension is "DMX".

-

-

-

-2. Syntactic conventions

-

-    This document uses the same syntactic conventions requests and data

-    types as [X11R6.4].

-

-

-

-3. Data types

-

-    No new data types are defined by this extension.  All data types

-    referenced in this document are defined in [X11R6.4].

-

-

-4. Requests

-

-    DMXQueryVersion

-        ==>

-        majorVersion: CARD32

-        minorVersion: CARD32

-        patchVersion: CARD32

-

-    The protocol this extension actually supports is indicated by

-    majorVersion and minorVersion (patchVersion indicates the

-    patchlevel and is for informational purposes only).

-

-    Any incompatible changes to the protocol should be indicated by

-    incrementing majorVersion.

-

-    Small, upward-compatible changes should be indicated by incrementing

-    minorVersion.

-

-    Servers that support the protocol defined in this document will

-    return a majorVersion of 1 and a minorVersion of 1.

-

-

-

-    DMXGetScreenCount

-        ==>

-        screenCount: CARD32

-

-    This request returns the number of back-end screens that the Xdmx

-    server controls.  A back-end screen may be managed as a regular X

-    screen in the Xdmx server or may be joined with other back-end

-    screens using Xinerama.  (The information returned by this request

-    does not change while Xdmx is running and may be cached on the

-    client side.)

-    

-

-

-    DMXGetScreenInformation

-        physicalScreen: CARD32

-        ==>

-        displayName: STRING8

-        width: CARD16

-        height: CARD16

-        xoffset: INT16

-        yoffset: INT16

-        logicalScreen: CARD32

-        xorigin: INT16

-        yorigin: INT16

-

-        Errors: Value

-

-    This request returns information about individual back-end screens.

-    The physicalScreen value is between 0 and screenCount-1, inclusive

-    (values outside this range will result in a Value error).  The

-    displayname is the name used to open the display, either from the

-    Xdmx command-line or from the configuration file.  The width,

-    height, xoffset, and yoffset values comprise a geometry

-    specification (see X(7x)) for the location of the DMX window on the

-    back-end screen.  This request will always return non-negative

-    (i.e., normalized) values for xoffset and yoffset.  The

-    logicalScreen value is the value of the screen that that Xdmx server

-    exports to clients.  When Xinerama is in use, this value is

-    typically 0 for all values of physicalScreen.  If Xinerama is in

-    use, the xorigin and yorigin values specify where the physical

-    screen is positioned in the global Xinerama coordinate system.

-    Otherwise, these values are set to 0.  (The information returned by

-    this request does not change while Xdmx is running and may be cached

-    on the client side.)

-    DMXGetWindowInformation

-        window: CARD32

-        ==>

-        screenCount: CARD32

-        screens: LISTofCARD32

-        windows: LISTofCARD32

-        pos: LISTofRECTANGLE

-        vis: LISTofRECTANGLE

-

-        Errors: Window, Alloc

-

-    This request computed the return values incorrectly for version 1.0

-    of this protocol.  Version 1.1 of this protocol conforms to this

-    description.

-

-    Given a window ID on the Xdmx server, this request returns data

-    about how the window is represented on the back-end X servers.  For

-    each back-end X server that displays a portion of the window, the

-    following information is returned:

-        1) the number of the physical screen containing that portion

-           (which can be used with the DMXGetScreenInformation request

-           to obtain more information about the screen),

-        2) the window ID on the back-end X server of the window

-           containing that portion,

-        3) the position and dimensions of the window on the back-end, in

-           screen coordinates, and

-        4) the visible area of the window on the back-end, in

-           window-relative coordinates (all zeros for windows that are

-           not visible)

-    Note that DMX allows multiple back-end windows to overlap in their

-    view of the DMX logical window.  Further, a logical window does not

-    have to be completely covered by back-end windows -- there may be

-    gaps.

-

-    As an example, consider a 500x500 window that spans the top two

-    1024x768 back-end displays (A and B) of a 2048x1536 DMX display

-    composed of 4 1024x768 back-end displays arranged in a cube:

-        A B

-        C D

-

-    In this case, the DMXGetWindowInformation call would return the

-    following information for the 500x500 window:

-

-    display A: 500x500 window at 1024-250,0 (relative to back end)

-               with 250x500 visible at 0,0 (relative to window origin)

-

-    display B: 500x500 window at -250,0 (relative to back end)

-               with 250x500 visible at 250,0 (relative to window origin)

-

-    display C: 500x500 window at 1024-250,-768 with 0x0 visible at 0,0

-

-    display D: 500x500 window at -250,-768 with 0x0 visible at 0,0

-

-    Note that if the specified window has not yet been mapped when

-    DMXGetWindowInformation is called, then a subsequent XMapWindow call

-    might be buffered in xlib while requests directly to the back-end X

-    servers are processed.  This race condition can be solved by calling

-    DMXSync before talking directly to the back-end X servers.

-

-

-    DMXGetInputCount

-        ==>

-        inputCount: CARD32

-

-    This request was first supported in version 1.1 of this protocol.

-

-    This request returns the number of input devices connected to the

-    Xdmx server.  This number is the same as that returned by

-    XListInputDevices, but is available even when the XInput extension

-    is not supported.

-

-

-

-    DMXGetInputInformation

-        deviceId: CARD32

-        ==>

-        inputType: CARD32

-        physicalScreen: CARD32

-        physicalId: CARD32

-        isCore: BOOL

-        sendsCore: BOOL

-        name: STRING8

-

-        Errors: Value

-

-    This request was first supported in version 1.1 of this protocol.

-

-    This request returns information about the specified input device

-    that cannot be obtained from the XListInputDeivices call.  The

-    deviceId is the same as that used by the XListInputDevices call, and

-    must be in the range 0 to inputCount-1, inclusive (values outside

-    this range will result in a Value error).

-

-    The value of inputType will always be value, and will be one of the

-    following values:

-        0 for local (and dummy) devices,

-        1 for console devices, and

-        2 for back-end devices.

-

-    For local devices, all other fields returned, except isCore and

-    sendsCore, are invalid.

-

-    For console devices, the physicalScreen and physicalID will be

-    invalid, and the name will return the name of the X server on which

-    the console window is displayed.

-

-    For back-end devices, the physicalScreen will identify the back-end

-    display and can be used as an argument to DMXGetScreenInformation to

-    obtain more information; the physicalId will be the XInput device id

-    on the back-end X server; and the name will be invalid (since it

-    does not provide any additional information that cannot be obtained

-    with DMXGetScreenInformation).

-

-    If isCore is True, then this device is active as a true core input

-    device and will send core events.  If sendsCore is True, then this

-    device queried an XInput extension device, but sends core events

-    instead of extension events.  Note that this behavior is different

-    from that of XFree86, where XInput extension devices may send both

-    extension events and core events.

-

-

-

-    DMXForceWindowCreation

-        window: CARD32

-        ==>

-

-        Errors: Window

-

-    This request was first supported in version 1.2 of this protocol.

-

-    When using the lazy window creation optimization, windows are not

-    created on the back-end X servers until they are required.  This

-    request forces the immediate creation of the window requested.

-

-

-

-    DMXReconfigureScreen

-        screen: CARD32

-        x: INT16

-        y: INT16

-        ==>

-        status: CARD32

-

-        Errors: Value

-

-    This request was first supported in version 1.3 of this protocol.

-

-    This request reconfigures the screen position to coordinates (x,y)

-    when using the Xinerama extension.  Otherwise, it is a NOP.  Illegal

-    values for screen will result in a BadValue error.  Other non-fatal

-    errors will be returned in status.

-

-

-

-    DMXSync

-        ==>

-

-    This request was first supported in version 1.5 of this protocol.

-

-    This request flushes all pending protocol requests between the Xdmx

-    server and each back-end X server.  It is used by a client that

-    talks directly to back-end X servers

-

-    To ensure proper synchronization semantics, this request has a

-    reply, but the reply does not carry any information.

+
+1. Overview
+
+    The client-to-server DMX extension to the X protocol (DMX) provides
+    normal client applications with the ability to determine information
+    about the characteristics of the Xdmx server and the back-end X
+    servers that DMX is using.
+
+    The name for this extension is "DMX".
+
+
+
+2. Syntactic conventions
+
+    This document uses the same syntactic conventions requests and data
+    types as [X11R6.4].
+
+
+
+3. Data types
+
+    No new data types are defined by this extension.  All data types
+    referenced in this document are defined in [X11R6.4].
+
+
+
+4. Requests
+
+    DMXQueryVersion
+        ==>
+        majorVersion: CARD32
+        minorVersion: CARD32
+        patchVersion: CARD32
+
+    The protocol this extension actually supports is indicated by
+    majorVersion and minorVersion (patchVersion indicates the
+    patchlevel and is for informational purposes only).
+
+    Any incompatible changes to the protocol should be indicated by
+    incrementing majorVersion.
+
+    Small, upward-compatible changes should be indicated by incrementing
+    minorVersion.
+
+    Servers that support the protocol defined in this document will
+    return a majorVersion of 1 and a minorVersion of 1.
+
+
+
+    DMXGetScreenCount
+        ==>
+        screenCount: CARD32
+
+    This request returns the number of back-end screens that the Xdmx
+    server controls.  A back-end screen may be managed as a regular X
+    screen in the Xdmx server or may be joined with other back-end
+    screens using Xinerama.  (The information returned by this request
+    does not change while Xdmx is running and may be cached on the
+    client side.)
+    
+
+
+    DMXGetScreenInformation
+        physicalScreen: CARD32
+        ==>
+        displayName: STRING8
+        width: CARD16
+        height: CARD16
+        xoffset: INT16
+        yoffset: INT16
+        logicalScreen: CARD32
+        xorigin: INT16
+        yorigin: INT16
+
+        Errors: Value
+
+    This request returns information about individual back-end screens.
+    The physicalScreen value is between 0 and screenCount-1, inclusive
+    (values outside this range will result in a Value error).  The
+    displayname is the name used to open the display, either from the
+    Xdmx command-line or from the configuration file.  The width,
+    height, xoffset, and yoffset values comprise a geometry
+    specification (see X(7x)) for the location of the DMX window on the
+    back-end screen.  This request will always return non-negative
+    (i.e., normalized) values for xoffset and yoffset.  The
+    logicalScreen value is the value of the screen that that Xdmx server
+    exports to clients.  When Xinerama is in use, this value is
+    typically 0 for all values of physicalScreen.  If Xinerama is in
+    use, the xorigin and yorigin values specify where the physical
+    screen is positioned in the global Xinerama coordinate system.
+    Otherwise, these values are set to 0.  (The information returned by
+    this request does not change while Xdmx is running and may be cached
+    on the client side.)
+
+
+
+    DMXGetWindowInformation
+        window: CARD32
+        ==>
+        screenCount: CARD32
+        screens: LISTofCARD32
+        windows: LISTofCARD32
+        pos: LISTofRECTANGLE
+        vis: LISTofRECTANGLE
+
+        Errors: Window, Alloc
+
+    This request computed the return values incorrectly for version 1.0
+    of this protocol.  Version 1.1 of this protocol conforms to this
+    description.
+
+    Given a window ID on the Xdmx server, this request returns data
+    about how the window is represented on the back-end X servers.  For
+    each back-end X server that displays a portion of the window, the
+    following information is returned:
+        1) the number of the physical screen containing that portion
+           (which can be used with the DMXGetScreenInformation request
+           to obtain more information about the screen),
+        2) the window ID on the back-end X server of the window
+           containing that portion,
+        3) the position and dimensions of the window on the back-end, in
+           screen coordinates, and
+        4) the visible area of the window on the back-end, in
+           window-relative coordinates (all zeros for windows that are
+           not visible)
+    Note that DMX allows multiple back-end windows to overlap in their
+    view of the DMX logical window.  Further, a logical window does not
+    have to be completely covered by back-end windows -- there may be
+    gaps.
+
+    As an example, consider a 500x500 window that spans the top two
+    1024x768 back-end displays (A and B) of a 2048x1536 DMX display
+    composed of 4 1024x768 back-end displays arranged in a cube:
+        A B
+        C D
+
+    In this case, the DMXGetWindowInformation call would return the
+    following information for the 500x500 window:
+
+    display A: 500x500 window at 1024-250,0 (relative to back end)
+               with 250x500 visible at 0,0 (relative to window origin)
+
+    display B: 500x500 window at -250,0 (relative to back end)
+               with 250x500 visible at 250,0 (relative to window origin)
+
+    display C: 500x500 window at 1024-250,-768 with 0x0 visible at 0,0
+
+    display D: 500x500 window at -250,-768 with 0x0 visible at 0,0
+
+    Note that if the specified window has not yet been mapped when
+    DMXGetWindowInformation is called, then a subsequent XMapWindow call
+    might be buffered in xlib while requests directly to the back-end X
+    servers are processed.  This race condition can be solved by calling
+    DMXSync before talking directly to the back-end X servers.
+
+
+    DMXGetInputCount
+        ==>
+        inputCount: CARD32
+
+    This request was first supported in version 1.1 of this protocol.
+
+    This request returns the number of input devices connected to the
+    Xdmx server.  This number is the same as that returned by
+    XListInputDevices, but is available even when the XInput extension
+    is not supported.
+
+
+
+    DMXGetInputInformation
+        deviceId: CARD32
+        ==>
+        inputType: CARD32
+        physicalScreen: CARD32
+        physicalId: CARD32
+        isCore: BOOL
+        sendsCore: BOOL
+        name: STRING8
+
+        Errors: Value
+
+    This request was first supported in version 1.1 of this protocol.
+
+    This request returns information about the specified input device
+    that cannot be obtained from the XListInputDeivices call.  The
+    deviceId is the same as that used by the XListInputDevices call, and
+    must be in the range 0 to inputCount-1, inclusive (values outside
+    this range will result in a Value error).
+
+    The value of inputType will always be value, and will be one of the
+    following values:
+        0 for local (and dummy) devices,
+        1 for console devices, and
+        2 for back-end devices.
+
+    For local devices, all other fields returned, except isCore and
+    sendsCore, are invalid.
+
+    For console devices, the physicalScreen and physicalID will be
+    invalid, and the name will return the name of the X server on which
+    the console window is displayed.
+
+    For back-end devices, the physicalScreen will identify the back-end
+    display and can be used as an argument to DMXGetScreenInformation to
+    obtain more information; the physicalId will be the XInput device id
+    on the back-end X server; and the name will be invalid (since it
+    does not provide any additional information that cannot be obtained
+    with DMXGetScreenInformation).
+
+    If isCore is True, then this device is active as a true core input
+    device and will send core events.  If sendsCore is True, then this
+    device queried an XInput extension device, but sends core events
+    instead of extension events.  Note that this behavior is different
+    from that of XFree86, where XInput extension devices may send both
+    extension events and core events.
+
+
+
+    DMXForceWindowCreation
+        window: CARD32
+        ==>
+
+        Errors: Window
+
+    This request was first supported in version 1.2 of this protocol.
+
+    When using the lazy window creation optimization, windows are not
+    created on the back-end X servers until they are required.  This
+    request forces the immediate creation of the window requested.
+
+
+
+    DMXReconfigureScreen
+        screen: CARD32
+        x: INT16
+        y: INT16
+        ==>
+        status: CARD32
+
+        Errors: Value
+
+    This request was first supported in version 1.3 of this protocol.
+
+    This request reconfigures the screen position to coordinates (x,y)
+    when using the Xinerama extension.  Otherwise, it is a NOP.  Illegal
+    values for screen will result in a BadValue error.  Other non-fatal
+    errors will be returned in status.
+
+
+
+    DMXSync
+        ==>
+
+    This request was first supported in version 1.5 of this protocol.
+
+    This request flushes all pending protocol requests between the Xdmx
+    server and each back-end X server.  It is used by a client that
+    talks directly to back-end X servers
+
+    To ensure proper synchronization semantics, this request has a
+    reply, but the reply does not carry any information.
