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.

      XMaxRequestSize returns the maximum request size (in 4-byte units)
      supported by the server.  Single protocol requests to the server can be
      no longer than this size.  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 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.
