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 .
