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.
