NAME
       XcupGetReservedColormapEntries - list colormap entries reserved by the system

SYNOPSIS
       cc [ flag ... ] file ... -lXext [ library ... ]
       #include <X11/extensions/Xcup.h>

       Status XcupGetReservedColormapEntries(Display *display,
	      int screen, XColor **colors_out, int *ncolors);

ARGUMENTS
       display	 Specifies the connection to the X server.

       screen	 Screen number on the host server.

       colors_out
		 Returns the values reserved by the server.

       ncolors	 Returns the number of items in colors_out.

DESCRIPTION
       The  XcupGetReservedColormapEntries  function  returns a list of colormap entries (pixels)
       that are reserved by the system. This list will, at a minimum,  contain	entries  for  the
       BlackPixel and WhitePixel of the specified screen. Use XFree to free colors_out.

       To  minimize colormap flash, an application which installs its own private colormap should
       query the special colors by calling XCupGetReservedColormapEntries,  and  can  then  store
       those entries (in the proper location) in its private colormap using XCupStoreColors.
