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.
