     ARGUMENTS
          display   Specifies the connection to the X server.

          screen_number
                    Specifies the appropriate screen number on the
                    host server.

          count_return
                    Returns the number of depths.

     DESCRIPTION
          The AllPlanes macro returns a value with all bits set to 1
          suitable for use in a plane argument to a procedure.

          The BlackPixel macro returns the black pixel value for the
          specified screen.

          The WhitePixel macro returns the white pixel value for the
          specified screen.

          The ConnectionNumber macro returns a connection number for
          the specified display.

          The DefaultColormap macro returns the default colormap ID
          for allocation on the specified screen.

          The DefaultDepth macro returns the depth (number of planes)
          of the default root window for the specified screen.

          The XListDepths function returns the array of depths that
          are available on the specified screen.  If the specified
          screen_number is valid and sufficient memory for the array
          can be allocated, XListDepths sets count_return to the
          number of available depths.  Otherwise, it does not set
          count_return and returns NULL.  To release the memory
          allocated for the array of depths, use XFree.
          The DefaultGC macro returns the default GC for the root
          window of the specified screen.

          The DefaultRootWindow macro returns the root window for the
          default screen.

          The DefaultScreenOfDisplay macro returns the default screen
          of the specified display.

          The DefaultScreen macro returns the default screen number
          referenced in the XOpenDisplay routine.

          The DefaultVisual macro returns the default visual type for
          the specified screen.

          The DisplayCells macro returns the number of entries in the
          default colormap.

          The DisplayPlanes macro returns the depth of the root window
          of the specified screen.

          The DisplayString macro returns the string that was passed
          to XOpenDisplay when the current display was opened.

          The XMaxRequestSize function returns the maximum request
          size (in 4-byte units) supported by the server without using
          an extended-length protocol encoding.  Single protocol
          requests to the server can be no larger than this size
          unless an extended-length protocol encoding is supported by
          the server.  The protocol guarantees the size to be no
          smaller than 4096 units (16384 bytes).  Xlib automatically
          breaks data up into multiple protocol requests as necessary
          for the following functions:  XDrawPoints, XDrawRectangles,
          XDrawSegments, XFillArcs, XFillRectangles, and XPutImage.

          The XExtendedMaxRequestSize function returns zero if the
          specified display does not support an extended-length
          protocol encoding; otherwise, it returns the maximum request
          size (in 4-byte units) supported by the server using the
          extended-length encoding.  The Xlib functions XDrawLines,
          XDrawArcs, XFillPolygon, XChangeProperty,
          XSetClipRectangles, and XSetRegion will use the extended-
          length encoding as necessary, if supported by the server.
          Use of the extended-length encoding in other Xlib functions
          (for example, XDrawPoints, XDrawRectangles, XDrawSegments,
          XFillArcs, XFillRectangles, XPutImage) is permitted but not
          required; an Xlib implementation may choose to split the
          data across multiple smaller requests instead.

          The LastKnownRequestProcessed macro extracts the full serial
          number of the last request known by Xlib to have been
          processed by the X server.
          The NextRequest macro extracts the full serial number that
          is to be used for the next request.

          The ProtocolVersion macro returns the major version number
          (11) of the X protocol associated with the connected
          display.

          The ProtocolRevision macro returns the minor protocol
          revision number of the X server.

          The QLength macro returns the length of the event queue for
          the connected display.

          The RootWindow macro returns the root window.

          The ScreenCount macro returns the number of available
          screens.

          The ScreenOfDisplay macro returns a pointer to the screen of
          the specified display.

          The ServerVendor macro returns a pointer to a null-
          terminated string that provides some identification of the
          owner of the X server implementation.

          The VendorRelease macro returns a number related to a
          vendor's release of the X server.
